Windows Error in Google App Engine

This is my first program in GAE. I'm working with latest GAE SDK, and Python 2.7 on Windows XP 32 bit. All was working fine; but to my surprise I'm getting the following error:

2013-03-20 22:48:26 Running command: "['C:\\Python27\\pythonw.exe', 'C:\\Program Files\\Google\\google_appengine\\dev_appserver.py', '--skip_sdk_update_check=yes', '--port=9080', '--admin_port=8001', u'B:\\AppEngg\\huddle-up']"

2013-03-20 22:48:27 (Process exited with code 1)

I Googled it; but it seems that most of the people getting this error have something wrong in there PATH config or in x64 Windows.

I got exactly the same problem with SDK 1.99 on Windows 8. I was running a test script .yaml and .go file from Google Go's own working directory. Moving my code to its own subdirectory solved the problem.

It might be that your "GOPATH" environment variable points to a directory that does not exist. To discover exactly what the offending directory is, make the following edit to win32_file_watcher.py (around line 60):

  """Start watching the directory for changes."""
+ print("Watching " + self._directory + "\n")
  self._find_change_handle = (

When you run the script again, you should see a printout of the last directory that it was trying to monitor for changes.

According to this thread, the new appserver has been pushed as default in 1.7.6 despite still having significant issues. http://www.mail-archive.com/[email protected]/msg67459.html

Although I am not having the same issue as you, I am getting fatal errors relating to python egg extraction which mean I can't use the new SDK. At this point the best thing is probably to revert to the earlier one: http://googleappengine.googlecode.com/files/GoogleAppEngine-1.7.5.msi

I had the same issue with GAE SDK 1.7.6, downgrading to 1.7.5 solved it for me too.

I updated GAE SDK to 1.7.6 from 1.7.5, since then I started getting this error. I reverted back to 1.7.5, the application is functioning normally :)
