The issue began when I was trying to install twilio on my Mac with El Capitan 10.11.6.

I got this error: 

    OSError: [Errno 1] Operation not permitted: '/tmp/pip-EmsRHo-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pyOpenSSL-0.13.1-py2.7.egg-info'

Research informed I should run pip install --ignore-installed six, which displayed the following error:

Exception:

    with open(dst, 'wb') as fdst:
IOError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/six.py'

Further research told me to run brew install python

I once again attempted to run pip install twilio

New error: 

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/Users/rdacso/Library/Python/2.7/lib/python/site-packages/pkg_resources/__init__.py", line 48, in <module>
    import six
ImportError: No module named six

I've attempted to pip install six, but continue to get this error:

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/Users/rdacso/Library/Python/2.7/lib/python/site-packages/pkg_resources/__init__.py", line 48, in <module>
    import six
ImportError: No module named six

Everything appears borked as a result of not having module six. I cannot install or uninstall six. Even pip freeze displays the ImportError: No module named six.

  • Have you tried `pip install --ignore-installed six` after installing python with `brew`? – wpercy May 09 '17 at 20:33
  • @wpercy Yes. Same issue: `Rebeccas-MacBook-Pro:gardening rdacso$ pip install --ignore-installed six Traceback (most recent call last): File "/usr/local/bin/pip", line 6, in from pkg_resources import load_entry_point File "/Users/rdacso/Library/Python/2.7/lib/python/site-packages/pkg_resources/__init__.py", line 48, in import six ImportError: No module named six` – rdacso May 09 '17 at 21:32

Turns out when I ran brew install python I managed to install a second python library. This caused dueling pythons.

I ran brew uninstall python, reinstalled pip using easy_install pip, which gave me the ability to once again pip install six.

After this was completed, I was able to install twilio using easy_install twilio rather than pip install twilio.
