Updating pip and setuptools in homebrew does not work

问题:

After brew install python, the following comes up:

Pip and setuptools have been installed. To update them   pip2 install --upgrade pip setuptools 

Running pip2 install

pip2 install --upgrade pip setuptools Traceback (most recent call last):   File "/usr/local/bin/pip2", line 11, in <module>     load_entry_point('pip==9.0.1', 'console_scripts', 'pip2')()   File "/Users/user1/Library/Python/2.7/lib/python/site-packages/pkg_resources/__init__.py", line 564, in load_entry_point     return get_distribution(dist).load_entry_point(group, name)   File "/Users/user1/Library/Python/2.7/lib/python/site-packages/pkg_resources/__init__.py", line 2661, in load_entry_point     raise ImportError("Entry point %r not found" % ((group, name),)) ImportError: Entry point ('console_scripts', 'pip2') not found

I was running into this after upgrading from Python 2.7.13 to 2.7.14 using Homebrew. I used the suggestion found in this issue on GitHub: https://github.com/pyenv/pyenv/issues/739 and it worked for me. The actual command I ran was:

/usr/local/Cellar/python/2.7.14/bin/python2 -m pip install --upgrade --force-reinstall pip

Good luck.
