I'm trying to setup flask with uwsgi. This is my directory structure:

/srv/http/www/myapp
|
+-- env -> virtualenv
|
+-- mpd -> the project directory
  |
  +-- main.py -> main application

And I'm using this command:

uwsgi -s 127.0.0.1:3002 --chdir webmpd --uid 33 --gid 33 --plugin python -H env --module main --callable app

And I get this error:

*** Starting uWSGI 1.9.19 (32bit) on [Sat Nov 30 22:37:33 2013] ***

Set PythonHome to env

ImportError: No module named 'encodings'

I have looked around a lot and this problem seems to be stemming from mismatched python version between uwsgi and the system, but in my case, both are running python 3.3. I don't know what else could be wrong.

Any help is appreciated.

Check your virtualenv (try removing it from the uWSGI options to see if the errors disappears) –  roberto Dec 1 '13 at 4:49
