Public bug reported:
When invoking "pip" on the command line, it immediately fails with:
$ pip
Traceback (most recent call last):
File "/usr/local/bin/pip", line 5, in <module>
from pkg_resources import load_entry_point
File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2676, in
<module>
parse_requirements(__requires__), Environment()
File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 552, in resolve
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: pip==0.8.2
Looking at the source, PIP is trying to use a load entry point that expects the
version of PIP to be 0.8.2. With it versioned as 1.0-1, the script internals
through a VersionConflict error and immediately terminates the script.
Following is the my work to determine what's causing the issue:
ubuntu@ubuntu:~$ python
Python 2.7.2+ (default, Oct 4 2011, 20:06:09)
[GCC 4.6.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> from pkg_resources import load_entry_point
>>> help(load_entry_point)
>>> load_entry_point('pip==0.8.2', 'console_scripts', 'pip')
