Question

I am using a Virtualenv on my Django install and have loaded in Pycrypto using

pip install pycrypto

after sourcing my environment.

When I try to import Crypto into my model, I get an import error, however if load the shell using

manage.py shell

it does load in, with out an issue.

I am pretty sure that django is running from the virtualenv as is it running 1.3.1 which more current than what is installed on the path and I have installed South via pip which is working.

I have also tried to install Pycrypto using

setup.py install

Any thoughts on how I fix/debug this?

Thanks

Edit:
I am relatively new to Django and Python so it could be something simple

Edit 2:
Hey Issac,

Is there any way that you can find all the modules getting loaded in?

I don’t understand why it wouldn’t work in browser but would work in the interactive shell? I am not saying that it can’t, i just don’t know if/how that could happen.

The import error as requested:

Answer 1

Just before the line which causes the import error insert this code:

import sys
assert False, sys.path

Compare both results.

In the shell (where you can import the module). You can do this:

import Crypto
assert False, Crypto.__file__

Is the directory of this result in sys.path of your webserver?
