I received this message: "No module named M2Crypto" I have already install M2Crypto with the command "pip install M2Crypto" and when I re-run it, I got the message: "Requirement already satisfied"

What's the problem with M2Crypto?

Thanks

ps: I use Linux: 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:12:00 UTC 2013 i686 i686 i686 GNU/Linux, Pycharm and Python2.7 (/usr/bin/python2.7)

Maybe some interpreter option in PyCharm configuration for running the project?

First of all, verify that the version of pip is in line with your interpreter. So for python2.7, 

pip --version

should print something like

pip 6.0.8 from /usr/local/lib/python2.7/dist-packages (python 2.7)

depending on how you've installed it. The important part is in the end, where your interpreter ("python 2.7") should be shown.

Once you're sure to have the right pip-version, ensure your package is correctly installed. It should usually be installed in the directory printed out previously by pip (e.g. /usr/local/lib/python2.7/dist-packages/).

Assume you've already done this, what else can go wrong to make your interpreter not finding the 'M2Crypto' package?

python uses the PYTHONPATH environment variable for module lookups. So, there's the possibility, that your PYTHONPATH variable has been changed. Try running your program by adding the above-mentioned path to PYTHONPATH and either exporting it before running your webserver:

export PYTHONPATH=/usr/local/lib/python2.7/dist-packages/:$PYTHONPATH
# run your server here

or by prepending the same variable to your command:

PYTHONPATH=/usr/local/lib/python2.7/dist-packages/:$PYTHONPATH python <run-stuff-here>

This should make your program find the M2Crypto module.
