Error With Installing Virtualenv With Pip and Homebrew

I am trying to get a nice clean Python environment setup on OSX 10.9. I've installed Python with Homebrew and set my PATH variables so...

> which python
/usr/local/bin/python

and

> which pip
/usr/local/bin/pip

so when I look at my /usr/local/bin :

pip -> ../Cellar/python/2.7.6/bin/pip
python -> ../Cellar/python/2.7.6/bin/python

then when I run:

> pip install virtualenv

I get permission errors on /usr/local/bin/virtualenv:

...
running install_scripts

Installing virtualenv script to /usr/local/bin

error: /usr/local/bin/virtualenv: Permission denied

I thought that by using Homebrew I could use pip and avoid using sudo to install virtualenv. Am I doing something wrong here?

Solution

  • Ok! I managed to fix this myself.

    I deleted all the virtualenv related things from /usr/local/bin (they had been installed under root for some reason and this was causing my permission issues.).

    Then I did a pip uninstall virtualenv to get rid of other instances of virtualenv, as there was still one in /usr/local/lib/python2.7/site-packages/

    Then a simple pip install virtualenv and things work fine now!
