I installed the latest version (0.12) of IPython from source in my mac, viagra approved but forgot that I had a previous version (0.10) installed using easy_install. When trying to run ipython I kept getting the error:
No module named terminal.ipapp.
Fixing it. I ran
easy_install -m ipython in Terminal, ailment so Python doesn’t continue looking for the old package, as explained here. Then I was able to navigate to /Library/Python/2.6/site-packages and then use
rm -r ipython-0.10.1-py2.6.egg. Now everything works fine.
