Hello, I'm working on an exercise to learn tg2 and mod_wsgi
integration.
The basic idea is to use a quickstarted tg2 app and immediately deploy
that
app using mod_wsgi.
I started with some templates from modwsgideploy.
I modified them to point to the right directories, and also fix some
directive
issues. (mod_wsgi couldn't see the virtual environment for instance.)
The work on this halted when I got to this point.
[Wed Aug 04 20:58:35 2010] [error] [client 127.0.0.1] Error - <type
'exceptions.OSError'>: [Errno 20] Not a directory: '/usr/local/
turbogears/BASELINE/lib/python2.5/site-packages/myapp-0.1dev-
py2.5.egg/
myapp/controllers'
The theme of the problem was that when "myapp" was installed it was
installed as
an egg file. The execution of the package just didn't happen.
I went to Graham's mod_wsgi's group to see if he could help. He
tried, but he
couldn't help proper like. Topic: A virtual environment thing?
(turbogears 2.0)
Google group: modwsgi.
Graham's final word was this:
>For whatever reason, Paste deploy isn't dealing with your zipped egg
>file. Suggest you install it as an expanded egg based package instead.
>
>Alternatively, you will need to go ask TG people whether one can have
>a site as zipped egg file and how to get it to work as I can't think
>of anything else to suggest.
