Question

I have a problem similar to this one below:

Python pip broken after OS X 10.8 upgrade

After installing ML, I can no longer use iPython, SciPy or Matplotlib. I get this error:

Shanes-MacBook-Pro:~ $ ipython
Traceback (most recent call last):
  File "/usr/local/bin/ipython", 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: ipython==0.14.dev

I have tried the following to fix it:

• Using sudo ipython
• Installing latest Xcode
• Reinstalling SciPy superpack

When I type which python it says it is in /usr/bin/python.

Extra information:

nside /Library/python/2.7/site-packages

Inside there is the following:

DateUtils-0.5.2-py2.7.egg
README
easy-install.pth
nose-1.1.2-py2.7.egg
pika-0.9.5-py2.7.egg
pyzmq-2.2.0.1-py2.7-macosx-10.8-intel.egg
tornado-2.3-py2.7.egg         

So with this ML upgrade, it removed my numpy, ipython, etc. And it does not install there anymore like it did with lion. How can I find where it installs too because it seems like it is working when I run the install_superpack shell script.

Answer 1

As an update, I never fixed this specific problem. However, I just downloaded the iPython, SciPy, Matplotlib etc. from Enthought. I answered someone elses question on how to do this here:

How to check whether I have IPython installed on my machine and what sequence to install these libraries?
