Python 2.7.9+ and 3.4+
Good news! Python 3.4 (released March 2014) and Python 2.7.9 (released December 2014) ship with Pip. This is the best feature of any Python release. It makes the community's wealth of libraries accessible to everyone. Newbies are no longer excluded from using community libraries by the prohibitive difficulty of setup. In shipping with a package manager, Python joins Ruby, Node.js, Haskell, Perl, Go--almost every other contemporary language with a majority open-source community. Thank you Python.
Of course, that doesn't mean Python packaging is problem solved. The experience remains frustrating. I discuss this in Stack Overflow question Does Python have a package/module management system?.
And, alas for everyone using Python 2.7.8 or earlier (a sizable portion of the community). There's no plan to ship Pip to you. Manual instructions follow.
Python 2 ≤ 2.7.8 and Python 3 ≤ 3.3
Flying in the face of its 'batteries included' motto, Python ships without a package manager. To make matters worse, Pip was--until recently--ironically difficult to install.
get-pip.py, being careful to save it as a
.pyfile rather than
.txt. Then, run it from the command prompt:
You possibly need an administrator command prompt to do this. Follow Start a Command Prompt as an Administrator (Microsoft TechNet).
This installs the pip package, which (in Windows) contains ...\Scripts\pip.exe that path must be in PATH environment variable to use pip from the command line (see the second part of 'Alternative Instructions' for adding it to your PATH,
The official documentation tells users to install Pip and each of its dependencies from source. That's tedious for the experienced and prohibitively difficult for newbies.
For our sake, Christoph Gohlke prepares Windows installers (
.msi) for popular Python packages. He builds installers for all Python versions, both 32 and 64 bit. You need to:
For me, this installed Pip at
pip.exeon your computer, then add its folder (for example,
C:\Python27\Scripts) to your path (Start / Edit environment variables). Now you should be able to run
pipfrom the command line. Try installing a package:
pip install httpie
There you go (hopefully)! Solutions for common problems are given below:
If you work in an office, you might be behind an HTTP proxy. If so, set the environment variables
https_proxy. Most Python applications (and other free software) respect these. Example syntax:
If you're really unlucky, your proxy might be a Microsoft NTLM proxy. Free software can't cope. The only solution is to install a free software friendly proxy that forwards to the nasty proxy. http://cntlm.sourceforge.net/
Unable to find vcvarsall.bat
Python modules can be partly written in C or C++. Pip tries to compile from source. If you don't have a C/C++ compiler installed and configured, you'll see this cryptic error message.
Error: Unable to find vcvarsall.bat
Often though it's easier to check Christoph's site for your package.点赞 评论分享

When I have to use Windows, I use ActivePython, which automatically adds everything to your PATH and includes a package manager called PyPM which provides binary package management making it faster and simpler to install packages.
easy_installaren't exactly the same thing, so there are some things you can get through
easy_installand vice versa.
My recommendation is that you get ActivePython Community Edition and don't worry about the huge hassle of getting everything set up for Python on Windows. Then, you can just use
In case you want to use
pipyou have to check the
PyPMoption in the ActiveState installer. After installation you only need to logoff and log on again, and
pipwill be available on the commandline, because it is contained in the ActiveState installer
PyPMoption and the paths have been set by the installer for you already.
PyPMwill also be available, but you do not have to use it.点赞 评论分享

-- Outdated -- use distribute, not setuptools as described here. --
-- Outdated #2 -- use setuptools as distribute is deprecated.
As you mentioned pip doesn't include an independent installer, but you can install it with its predecessor easy_install.
- Download the last pip version from here: http://pypi.python.org/pypi/pip#downloads
- Uncompress it
- Download the last easy installer for Windows: (download the .exe at the bottom of http://pypi.python.org/pypi/setuptools ). Install it.
- copy the uncompressed pip folder content into
C:\Python2x\folder (don't copy the whole folder into it, just the content), because python command doesn't work outside
C:\Python2xfolder and then run:
python setup.py install
- Add your python
C:\Python2x\Scriptsto the path
You are done.
Now you can use
pip install packageto easily install packages as in Linux :)点赞 评论分享

1) If you have installed Python 3.4 or later, pip is included with Python and should already be working on your system.
2) If you are running a version below Python 3.4 or if pip was not installed with Python 3.4 for some reason, then you'd probably use pip's official installation script
get-pip.py. The pip installer now grabs setuptools for you, and works regardless of architecture (32-bit or 64-bit).
The installation instructions are detailed here and involve:
To install or upgrade pip, securely download get-pip.py.
Then run the following (which may require administrator access):
To upgrade an existing setuptools (or distribute), run
pip install -U setuptools
I'll leave the two sets of old instructions below for posterity.
For Windows editions of the 64 bit variety - 64-bit Windows + Python used to require a separate installation method due to ez_setup, but I've tested the new distribute method on 64-bit Windows running 32-bit Python and 64-bit Python, and you can now use the same method for all versions of Windows/Python 2.7X:
OLD Method 2 using distribute:
- Download distribute - I threw mine in
C:\Python27\Scripts(feel free to create a
Scriptsdirectory if it doesn't exist.
- Open up a command prompt (on Windows you should check out conemu2 if you don't use PowerShell) and change (
cd) to the directory you've downloaded
- Run distribute_setup:
python distribute_setup.py(This will not work if your python installation directory is not added to your path - go here for help)
- Change the current directory to the
Scriptsdirectory for your Python installation (
C:\Python27\Scripts) or add that directory, as well as the Python base installation directory to your %PATH% environment variable.
- Install pip using the newly installed setuptools:
The last step will not work unless you're either in the directory
easy_install.exeis located in (C:\Python27\Scripts would be the default for Python 2.7), or you have that directory added to your path.
OLD Method 1 using ez_setup:
Download ez_setup.py and run it; it will download the appropriate .egg file and install it for you. (Currently, the provided .exe installer does not support 64-bit versions of Python for Windows, due to a distutils installer compatibility issue.
After this, you may continue with:
c:\Python2x\Scriptsto the Windows path (replace the
Python2xwith the actual version number you have installed)
- Open a new (!) DOS prompt. From there run
- Download distribute - I threw mine in

On Windows, simply download and install first
pipfrom the above links. The
distributelink above does contain stub
.exeinstallers, and these are currently 32-bit only. I haven't tested the effect on 64-bit Windows.
Building on Windows
The process to redo this for new versions is not difficult, and I've included it here for reference.
In order to get the stub
.exefiles, you need to have a Visual C++ compiler (it is apparently compilable with MinGW as well)
hg clone https://bitbucket.org/tarek/distribute cd distribute hg checkout 0.6.27 rem optionally, comment out tag_build and tag_svn_revision in setup.cfg msvc-build-launcher.cmd python setup.py bdist_win32 cd .. echo build is in distribute\dist
git clone https://github.com/pypa/pip.git cd pip git checkout 1.1 python setup.py bdist_win32 cd .. echo build is in pip\dist点赞 评论分享

Updated at 2016 :
Pipshould already be included in
Python 2.7.9+ or 3.4+, but if for whatever reason it is not there, you can use the following one-liner.
- Download https://bootstrap.pypa.io/get-pip.py and run it with Administrator permission
python get-pip.py(If you are on Linux, use
sudo python get-pip.py)
This should already be satisfied in most cases but, if necessary, be sure that your environment variable PATH includes Python's folders (for example,
Python 2.7.xon Windows default install:
C:\Python27 and C:\Python27\Scripts, for
C:\Python33 and C:\Python33\Scripts, etc)
I encounter same problem and then found such perhaps easiest way (one liner!) mentioned on official website here: http://www.pip-installer.org/en/latest/installing.html
Can't believe there are so many lengthy (perhaps outdated?) answers out there. Feeling thankful to them but, please up-vote this short answer to help more new comers!点赞 评论分享
- Download https://bootstrap.pypa.io/get-pip.py and run it with Administrator permission

These answers are outdated or otherwise wordy and difficult.
If you've got Python 3.4+ or 2.7.9+, it will be installed by default on Windows. Otherwise, in short:
- Download the pip installer: https://bootstrap.pypa.io/get-pip.py
- If paranoid, inspect file to confirm it isn't malicious (must b64 decode).
- Open a console in the download folder as Admin and run
get-pip.py. Alternatively, right-click its icon in Explorer and choose the "run as Admin...".
The new binaries
pip.exe(and the deprecated
easy_install.exe) will be found in the
"%ProgramFiles%\PythonXX\Scripts"folder (or similar), which is likely not in your
PATHvariable. I recommend adding it.点赞 评论分享

Update March 2015
Python 2.7.9 and later (on the Python 2 series), and Python 3.4 and later include pip by default, so you may have pip already.
If you don't, run this one line command on your prompt (which may require administrator access):
python -c "exec('try: from urllib2 import urlopen \nexcept: from urllib.request import urlopen');f=urlopen('https://bootstrap.pypa.io/get-pip.py').read();exec(f)"
As mentioned in comments, the above command will download code from the Pip source code repository at GitHub, and dynamically run it at your environment. So be noticed that this is a shortcut of the steps download, inspect and run, all with a single command using Python itself. If you trust Pip, proceed without doubt.
Be sure that your Windows environment variable PATH includes Python's folders (for Python 2.7.x default install:
C:\Python27\Scripts, for Python 3.3x:
C:\Python33\Scripts, and so on).点赞 评论分享

The best way I found so far, is just two lines of code:

To use pip, it is not mandatory that you need to install pip in the system directly. You can use it through
virtualenv. What you can do is follow these steps:
- Download virtualenv tar.gz file from https://pypi.python.org/pypi/virtualenv
- Unzip it with 7zip or some other tool
We normally need to install Python packages for one particular project. So, now create a project folder, let’s say myproject.
- Copy the virtualenv.py file from the decompressed folder of
virtualenv, and paste inside the myproject folder
Now create a virtual environment, let’s say myvirtualenv as follows, inside the myproject folder:
python virtualenv.py myvirtualenv
It will show you:
New python executable in myvirtualenv\Scripts\python.exe Installing setuptools....................................done. Installing pip.........................done.
Now your virtual environment, myvirtualenv, is created inside your project folder. You might notice, pip is now installed inside you virtual environment. All you need to do is activate the virtual environment with the following command.
You will see the following at the command prompt:
(myvirtualenv) PATH\TO\YOUR\PROJECT\FOLDER>pip install package_name
Now you can start using pip, but make sure you have activated the virtualenv looking at the left of your prompt.
This is one of the easiest way to install pip i.e. inside virtual environment, but you need to have virtualenv.py file with you.
For more ways to install pip/virtualenv/virtualenvwrapper, you can refer to thegauraw.tumblr.com.点赞 评论分享

The up-to-date way is to use Windows' package manager Chocolatey.
Once this is installed, all you have to do is open a command prompt and run the following the three commands below, which will install Python 2.7, easy_install and pip. It will automatically detect whether you're on x64 or x86 Windows.
cinst python cinst easy.install cinst pip
All of the other Python packages on the Chocolatey Gallery can be found here.点赞 评论分享

It's very simple:
Step 1: wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py Step 2: wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py Step 2: python ez_setup.py Step 3: python get-pip.py

C:\Python27\Scripts) are in the PATH.)点赞 评论分享

I had some issues installing in different ways when I followed instructions here. I think it's very tricky to install in every Windows environment in the same way. In my case I need Python 2.6, 2.7 and 3.3 in the same machine for different purposes so that's why I think there're more problems. But the following instructions worked perfectly for me, so might be depending on your environment you should try this one:
Also, due to the different environments I found incredible useful to use Virtual Environments, I had websites that use different libraries and it's much better to encapsulate them into a single folder, check out the instructions, briefly if PIP is installed you just install VirtualEnv:
pip install virtualenv
Into the folder you have all your files run
And seconds later you have a virtual environment with everything in venv folder, to activate it run venv/Scripts/activate.bat (deactivate the environment is easy, use deactivate.bat). Every library you install will end up in venv\Lib\site-packages and it's easy to move your whole environment somewhere.
The only downside I found is some code editors can't recognize this kind of environments, and you will see warnings in your code because imported libraries are not found. Of course there're tricky ways to do it but it would be nice editors keep in mind Virtual Environments are very normal nowadays.
Hope it helps.点赞 评论分享

Working as of Feb 04 2014 :):
If you have tried installing pip through the Windows installer file from http://www.lfd.uci.edu/~gohlke/pythonlibs/#pip as suggested by @Colonel Panic, you might have installed the pip package manager successfully, but you might be unable to install any packages with pip. You might also have got the same SSL error as I got when I tried to install Beautiful Soup 4 if you look in the pip.log file:
Downloading/unpacking beautifulsoup4 Getting page https://pypi.python.org/simple/beautifulsoup4/ Could not fetch URL https://pypi.python.org/simple/beautifulsoup4/: **connection error: [Errno 1] _ssl.c:504: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed** Will skip URL https://pypi.python.org/simple/beautifulsoup4/ when looking for download links for beautifulsoup4
Installing Pip on Windows:
- Download pip 1.2.1 from https://pypi.python.org/packages/source/p/pip/pip-1.2.1.tar.gz
- Extract the pip-1.2.1.tar.gz file
- Change directory to the extracted folder:
cd <path to extracted folder>/pip-1.2.1
python setup.py install
- Now make sure
C:\Python27\Scriptsis in PATH because pip is installed in the
C:\Python27\Lib\site-packageswhere Python packages are normally installed
Now try to install any package using pip.
For example, to install the
requestspackage using pip, run this from cmd:
pip install requests
requestswill be successfully installed and you will get a success message.点赞 评论分享

The following works for Python 2.7. Save this script and launch it:
Pip is installed, then add the path to your environment :
pip install virtualenv
Also you need Microsoft Visual C++ 2008 Express to get the good compiler and avoid these kind of messages when installing packages:
error: Unable to find vcvarsall.bat

- Switch from one Python interpreter (i.e. version) to another (including py and pypy)
- See all installed packages, and whether they are up-to-date
- Install or upgrade a package, or upgrade pip itself
- Create and delete virtual environments, and switch between them
- Run the IDLE or another Python script, with the selected interpreter

I use the cross-platform Anaconda package manager from continuum.io on Windows and it is reliable. It has virtual environment management and a fully featured shell with common utilities (e.g. conda, pip).
> conda install <package> # access distributed binaries > pip install <package> # access PyPI packages
condaalso comes with binaries for libraries with non-Python dependencies, e.g.
numpy, etc. This proves useful particularly on Windows as it can be hard to correctly compile C dependencies.点赞 评论分享

I think the question makes it seem like the answer is simpler than it really is. Running of pip will sometimes require native compilation of a module (64-bit Numpy is a common example of that). In order for pip's compilation to succeed, you need Python which was compiled with the same version of MSVC as the one pip is using. Standard Python distributions are compiled with MSVC 2008. You can install an Express version of VC2008, but it is not maintained. Your best bet is to get an express version of a later MSVC and compile Python. Then PIP and Python will be using the same MSVC version.点赞 评论分享

pip is already installed if you're using Python 2 >=2.7.9 or Python 3 >=3.4 binaries downloaded from python.org, but you'll need to upgrade pip.
On Windows upgrade can be done easily
Go to Python command line and run below Python command
python -m pip install -U pip
Installing with get-pip.py
Download get-pip.py in the same folder or any other folder of your choice. I am assuming you will download it in the same folder from you have python.exe file and run this command
Pip's installation guide is pretty clean and simple.
Using this you should be able to get started with Pip in under two minutes.点赞 评论分享
