PyQT 4.9.1 formula deletes site-packages

[devonbryant]

After running an upgrade on the latest PyQT (4.9.1), it removed my previous "/usr/local/lib/python2.7/site-packages" directory and created a symlink to "site-packages -> ../../Cellar/pyqt/4.9.1/lib/python2.7/site-packages", which only contains the PyQt4 package.

Mmm... that is odd and disturbing. This is probably a result of 2bf9bba, but I ran that code on my own machine before pushing it and nothing of the sort happened.

Was your site-packages directory empty prior to installing PyQt?

pyqt doesn't work for me. Here is the error output

$ find /usr/local -name "sipconfig*"
/usr/local/Cellar/sip/4.13.2/lib/python2.7/site-packages/sipconfig.py
/usr/local/lib/python2.7/site-packages/sipconfig.py

I'm not sure how this happened and have not been able to re-produce it. I just removed and re-installed python/pyqt/sip and everything installed correctly this time.

@2bits I was having strange issues due to *.pyc files being left behind in the old SIP and PyQt link destination: HOMEBREW_PREFIX/lib/python. I would suggest cleaning that directory out and taking it off the PYTHONPATH.

I noticed Devon said he installed Python. So I tried that, and pyqt installs correctly. It fails for me otherwise, even if I do a

brew rm -f `brew list`

and remove everything in /usr/local/lib/* then rebrew.

And is the following directory on your PYTHONPATH (as per the sip caveats)?

/usr/local/lib/python2.7/sitepackages

Homebrew's Python 2.7 knows to look in /usr/local/lib/python2.7/site-packages. The system Python has to be told where to look.

Oops. My .profile had the old PYTHONPATH. Thanks for figuring that out for me.

Maybe we need to audit PYTHONPATH too in brew doctor.
