Is there a definitive guide for how to install Homebrew’s Python properly, along with pip, virtualenv, virtualenvwrapper etc.?
I’ve read the following pages:

I have OSX 10.8 (Mountain Lion) DP3, and I installed the XCode Command Line Tools.
I also installed XQuartz as well, just in case (10.8 doesn’t provide it).
I then ran:
brew install python --universal --framework
I added the following to my ~/.bash_profile:
export PATH="/usr/local/bin:/usr/local/share/python:${PATH}"
I then ran:
sudo easy_install pip
which seemed to work.
I check where pip’s installed:
Victors-MacBook-Pro:~ victorhooi$ which pip
/usr/local/bin/pip
However, when I try to pip install packages, I get an error complaining about not being able to write to /Library/Python/2.7/site-packages:
running install_lib
creating /Library/Python/2.7/site-packages/yolk
error: could not create '/Library/Python/2.7/site-packages/yolk': Permission denied
----------------------------------------
Command /usr/bin/python -c "import setuptools;__file__='/Users/victorhooi/build/yolk/setup.py';exec(compile(open(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --single-version-externally-managed --record /var/folders/gg/m37t1rkx4zj7z54ls487jfc40000gn/T/pip-ap7LSB-record/install-record.txt failed with error code 1 in /Users/victorhooi/build/yolk
Storing complete log in /Users/victorhooi/Library/Logs/pip.log
My understanding was that Homebrew’s Python would install into it’s own site-packages, and I wouldn’t need to do weird chown’s all over the filesystem tree to get things to work?
Cheers,
Victor
Please, as someone who has been exactly where you are, start using virtual environments first, then pip and the rest. They are awesome, and will solve this and many future problems.
