When trying to install virtualenv using a brewed python, I get the following error: $ pip install virtualenv Requirement already satisfied (use --upgrade to upgrade): \ virtualenv in /Library/Python/2.7/site-packages/virtualenv-1.9.1-py2.7.egg Cleaning up... So clearly pip is somehow looking into the system python folder instead of the brewed one in /usr/local. How can I avoid this? The brew doctor finds no problems, and the path priority is set ok. I tried to remove the virtualenv package from the system python, so I could install virtualenv with the brewed pip. But then I could not create virtualenvs, as I got this error: $ virtualenv datatransfer/ Traceback (most recent call last): File "/usr/local/bin/virtualenv", line 5, in <module> from pkg_resources import load_entry_point File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2603, in <module> working_set.require(__requires__) File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 666, in require needed = self.resolve(parse_requirements(requirements)) File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 565, in resolve raise DistributionNotFound(req) # XXX put more info here pkg_resources.DistributionNotFound: virtualenv==1.9.1 So I have not managed to avoid the system virtualenv. What I am doing wrong?
