uWSGI resets PythonHome

Question

I am using nginx+django+uwsgi to deploy my application, but I found that it doesn't work on my host. The error is like this:

[uWSGI] parsing config file forum/uwsgi.xml
*** Starting uWSGI 2.0.1 (64bit) on [Tue Feb 11 10:42:47 2014] ***

Set PythonHome to /home/foo/software/uwsgi-2.0.1
ImportError: No module named site

I deploy it in my local computer, and it works. How do I solve this problem?

The config file is as follows:

<uwsgi>
  <socket>127.0.0.1:8630</socket>
  <chdir>/home/foo/git/project/forum</chdir>
  <module>wsgi</module>
</uwsgi>

and the the console output on my local computer is :

If you're not using Virtualenv, you must add the pythonpath directive to your config file:

pythonpath = /usr/local/lib/python2.7/dist-packages
pythonpath = /usr/lib/python2.7

This is in the .ini syntax, please adapt it to your XML configuration.
