Question

I am trying to install the python-oath2 library in my Python virtual environment running python 2.7.3 via Pythonbrew on a Dreamhost shared hosting file.

First I downloaded the tarball on this link and then extracted the file contents.
https://github.com/simplegeo/python-oauth2

I then cded into the extracted folder and then ran

python setup.py build
python setup.py install

This produced a new file oauth2-1.5.211-py2.7.egg in the directory

/home/davidfaux/.pythonbrew/pythons/Python-2.7.3/lib/python2.7/site-packages

When I import oauth2 in the Python interpreter, no errors surface. However, when I call import oauth2 in views.py of my Django application, an error is raised:

Could not import myapp.views. Error was: No module named oauth2

I tried restarting Passenger (touch tmp/restart.txt), restarting Python (pkill python), and re-sshing into the server. I also tried pb switch 2.7.3 to ensure that I was using the right version of Python. Why doesn’t Django let me import oauth2 if importing it works in the Python interpreter?

Answer 1

The process running your django application is either:

1. Not using your custom Python, so it cannot find your package
2. Has a different directory listed in PYTHONPATH for packages, and it cannot find it.
3. Finally, if both those aren’t true – try removing all *.pyc files using something like this – find . -name *.pyc -exec rm {} \; and restart your backend server (passenger).
