Why is Python easy_install not working on my Mac?

I have a Mac running Python 2.6. When I try to use easy_install I get this message:

/usr/bin/easy_install-2.6:7: UserWarning: Module pkg_resources was already imported from /System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/pkg_resources.pyc, but /Library/Python/2.6/site-packages is being added to sys.path
  from pkg_resources import load_entry_point

  from pkg_resources import load_entry_point
Traceback (most recent call last):
  File "/usr/bin/easy_install-2.6", line 10, in <module>
    load_entry_point('setuptools==0.6c9', 'console_scripts', 'easy_install')()
  File "/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/pkg_resources.py", line 271, in load_entry_point
    return False

    deps = []
ImportError: Entry point ('console_scripts', 'easy_install') not found

I am very confused by this and I want to know how I can fix this. Previously I didn't get this message, then after installing pip and uninstalling it, easy_install no longer works. I was wondering how I could fix this, or restore the default Python or easy_install setting on Mac.

I had the same problem just after installing the new Operating System (Lion OSX). After install python and execute it

sudo easy_install ipython
ipython

I got the following error:

Traceback (most recent call last):
  File "/usr/local/bin/ipython", line 8, in <module>
    load_entry_point('ipython==0.10.2', 'console_scripts', 'ipython')()
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 318, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2220, in load_entry_point
    raise ImportError("Entry point %r not found" % ((group,name),))
ImportError: Entry point ('console_scripts', 'ipython') not found

Then I realize it was a permission problem. If I execute the ipython script as sudo it worked.

sudo ipython

So I changed the ownership from root to my user () of the folder /Library/Python/2.7/site-packages/

sudo chown -R <your_user>:wheel /Library/Python/2.7/site-packages/

Use change ownership only if you don't have several accounts that uses python.

I hope it work for you.

I had a similar error message after following similar steps. I suspect it's because I tried to install the distribute module, and it tried to install a new version of setuptools which didn't quite work because it failed to correctly override the Mac OS X supplied setuptools. But that's only a suspicion.

I fixed my problem by doing the following. I found that the directory /System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python had 4 files with .OLD in the name. When I did a compare with similarly named files without the .OLD from when things worked (via Time Machine) I found that they were the same except for the name. So I did the following renames:

setuptools.OLD.1305936263.57 -> setuptools
setuptools-0.6c9-py2.6.egg-info.OLD.1305936263.57 -> setuptools-0.6c9-py2.6.egg-info
pkg_resources.py.OLD.1305936263.57 -> pkg_resources
site.py.OLD.1305936263.59 -> site.py

I had to use the command line and sudo mv because the files are owned by root. For example: sudo mv setuptools.OLD.1305936263.57 setuptools. You'll have to enter your password.

The other thing I did was clean the /Library/Python/2.6/site-packages directory. I used Time Machine to set it back to its pre-messed up state. If you don't have Time Machine, then you should be able to recover if you delete any files or folders beginning with distribute, easy-install, pip, pkg_resources, setuptools and site.

If that doesn't do the trick, uninstall any modules you can from that directory. For example use pip uninstall if you installed modules with pip. The reason to do this is that installation can copy files into usr/local/bin and other places that pip will remove for you.

Next it's time to remove any remaining modules. Rename the folder (in case ther
