Problems using nose in a virtualenv

Question

I am unable to use nose (nosetests) in a virtualenv project - it can't seem to find the packages installed in the virtualenv environment.

The odd thing is that i can set

test_suite = 'nose.collector' 

in setup.py and run the tests just fine as

python setup.py test 

but when running nosetests straight, there are all sorts of import errors.

I've tried it with both a system-wide installation of nose and a virtualenv nose package and no luck.

Any thoughts?

Thanks!!

You need to have a copy of nose installed in the virtual environment. In order to force installation of nose into the virtualenv, even though it is already installed in the global site-packages, run pip install with the -I flag:

(env1)$ pip install nose -I 

From then on you can just run nosetests as usual.
