What is causing ImportError: No module named pkg_resources after upgrade of Python on os X?
I just updated Python to 2.6.4 on my Mac. I installed from the dmg package.
The binary did not seem to correctly set my Python path, so I added '/usr/local/lib/python2.6/site-packages' in .bash_profile
>>> pprint.pprint(sys.path)
['',
'/Users/Bryan/work/django-trunk',
'/usr/local/lib/python2.6/site-packages',
'/Library/Frameworks/Python.framework/Versions/2.6/lib/python26.zip',
'/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6',
'/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-darwin',
'/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-mac',
'/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-mac/lib-scriptpackages',
'/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-tk',
'/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-old',
'/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload',
'/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages']
Apparently that is not all the required paths because I can't run iPython.
$ ipython
Traceback (most recent call last):
File "/usr/local/bin/ipython", line 5, in <module>
from pkg_resources import load_entry_point
ImportError: No module named `pkg_resources`
I've done Google searches and I can't really figure out how to install pkg_resources or make sure it's on the path.
What do I need to do to fix this?
Answer
I encountered the same ImportError. Somehow the setuptools package had been deleted in my Python environment.
To fix the issue, run the setup script for setuptools:
curl https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py | python
If you have any version of distribute, or any setuptools below 0.6, you will have to uninstall it first.*
See Installation Instructions for further details.
* If you already have a working distribute, upgrading it to the "compatibility wrapper" that switches you over to setuptools is easier. But if things are already broken, don't try that.
