如何从头开始在Windows上正确配置GAE Go SDK和GoClipse？

Question

I've been a GAE Go developer for a year now, and seeing that the SDK became available on Windows, I figured I'd try it out. However, I am having problems finding any documentation on how to install it properly from scratch. I have no idea what steps to take to ensure that my projects will be running properly, so I'd like to know what is the proper way to install and configure Google App Engine Go SDK and GoClipse on Windows?

Same here. The GAE GO SDK needs some more Windows install instructions...

As of today 2012-07-28 I just got it working on Win 7 by:

• downloading the App Engine SDK for GO here: developers.google.com/appengine/downloads#Google_App_Engine_SDK_for_Go and selected the Win 32 bit in my case googleappengine.googlecode.com/files/go_appengine_sdk_windows_386-1.7.0.zip

• I unzipped the GO SDK in C:\googleappenginego (make it the name you like).

• Then I added that folder path to the PATH environment variable in th System settings Advanced Settings:

My "Path" is set at:

C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\ThinkPad\Bluetooth Software\;C:\Program Files\ThinkPad\Bluetooth Software\syswow64;C:\Program Files (x86)\Common Files\Lenovo;C:\Program Files (x86)\Common Files\Ulead Systems\MPEG;C:\Program Files (x86)\Windows Live\Shared;C:\SWTOOLS\ReadyApps;%JAVA_HOME%\bin;C:\googleappenginego\

• I installed Python 2.7.3 from: www.python.org/download/ selected this version: www.python.org/ftp/python/2.7.3/python-2.7.3.msi I installed it in the default folder C:\Python27 by launching the python-2.7.3.msi file

• I created the GO GAE project as indicated in the GAE GO Getting Started series: developers.google.com/appengine/docs/go/gettingstarted/helloworld

• After creating the C:\myapp\app.yaml and C:\myapp\hello\hello.go, launch the project by opening a cmd window from the Win "Start/Run..." menu.

Then type in: "dev_appserver.py c:\myapp\" You should see something like:

Then go into your browser and go to "http://localhost:8080" to see your app or "http://localhost:8080/_ah/admin/" for the admin console.

Change the hello.go file, change "Hello, world" to "Hello, galaxy" for example and refresh the localhost:8080 browser window. It should show the new message without crashing or restarting the server. See right below:

NOTE: don't install Python 2.5.x, that was my initial mistake, despite what the GO SDK says. It will run but it dies when I modify the hello.go source code and refresh the browser window with some like that:

<type 'exceptions.AttributeError'>: 'module' object has no attribute 'kill' 
      args = ("'module' object has no attribute 'kill'",) 
      message = "'module' object has no attribute 'kill'"
