Fatal error in grunt (trying to serve docs)

[ebert...@gmail.com]

I'm trying to use Polymer with Jekyll, so I'm starting trying to locally run the Polymer docs. If I run 'grunt docs', it will build correctly. But I'm having an issue with the app engine server. If I run 'grunt', I get:

Running "appengine:run:frontend" (appengine) task

executing: dev_appserver.py --port=3000 --host=0.0.0.0 .

Fatal error: spawn dev_appserver.py ENOENT

    Warning:  Use --force to continue.

        

        Aborted due to warnings.

Full output: http://pastebin.com/T3ZFAiQw

I'm using the Python app engine SDK (that was an issue in another thread) and  Python 2.7.9.

I had the same issue and it ended up being a good 'ol configuration error in my $PATH environment variable.
