装了python3.7 大包的时候显示python3不是内部或外部指令_course

环境是windows10，官网下载了python3.7 安装的时候也勾选了Add to path选项，看到环境变量里也有python的路径，但是运行Head first python里面大包的例子的时候显示python3不是内部或者外部指令如图：  但是运行python setup.py sdist可以识别python指令，但是报语法错误。请问怎么设置才能打包成功呢

安装python 后启动不了python程序_course

安装python 后启动不了python程序，提示“由于应用程序配置不正确，应用程序未能启动。重新安装应用程序可能会纠正这个问题”。我重新安装后还是老错误。经过搜索，有人说是没用安装vc studio ，但是安装后仍旧不行。 <br />头一回遇到这错，难度要重装系统？ <br /><img src="/images/smiles/icon_redface.gif"/> <br/><strong>问题补充</strong><br/>谢谢楼上的两位。不是环境变量的问题，这点我可以肯定。 <br />我装的是visual&nbsp; C++ 2008 express。所以，肯定也不是runtime的问题。而且我把那几个dll都拷贝到system32下面去了，还是不行。我试过其他的几个版本了，还有那些集成的环境，都不行。在cmd窗口，切换到python目录运行python，提示无非运行指定的程序

关于Mac下python pip版本问题以及pycharm安装python第三方库失败问题_course

我的电脑是mac 10.15版本 目前有两个python： 1. 系统自带Python 2.7.16 2. 自己安装python Python 3.7.3 在终端查询pip版本，结果是2.7的那个： pip 19.3.1 from /Library/Python/2.7/site-packages/pip (python 2.7) 查询pip3，结果显示错误： xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun 好像问题就是在这里，我在终端用 pip install 安装python第三方库的时候总会有问题，提示pip版本过低，我想更新pip又会失败；或者根本无法安装。 然后我就选择从pycharm上搜索第三方库并安装，奇怪的是有的库可以成功安装，有的库安装失败并提示说pip版本过低，让我尝试从终端安装，可是从终端安装的话又会遇到之前的问题。 请问这个该怎么解决？

如何指定uwsgi在启动时默认的python版本_course

最近用django写了个项目,用的是python3.6，想放在服务器上用uwsgi+nginx运行的，因为服务器默认的是python2.7，所以我在服务器上安装了python3并创建软连接，这是我的uwsgi的配置文件,名字叫uwsgi.ini：  我的项目在python2中运行不了，但是uwsgi启动时默认的是python2，所以我在配置文件中加了这样一句：plugin=python3 然后当我执行命令：uwsgi --ini uwsgi.ini时出现问题：  我也知道问题在这里， open（“./ python3_plugin.so”）：没有这样的文件或目录[core / utils.c line 3724] ！无法加载uWSGI插件：./ python3_plugin.so：无法打开共享对象文件：没有这样的文件或目录！ 但是我不知道创建这个文件之后我应该做什么？ 恳请大佬解答。

C/C++ 与 Python 的通信-- python高手指导哈_course

我在python中传递一个函数指针给C编写的dll, 在dll中保存回调函数指针，并且开启一个线程，间隔调用此回调函数，函数可以正常运行（函数里面就一条打印语句），但是没有进入python定义的函数体执行，而回调函数可以正常执行，看起来应该是重新开辟了一块内存，将python的这个回调函数进拷贝过去了。这是咋回事，如何解决？
