I'm seeing the following error when trying to run pip after having just installed, on MacOS:

What should I do to correct that?
Maybe just reinstall Python, I had that issue and it worked for me. Another solution, that I didn't test is using this python file https://bootstrap.pypa.io/get-pip.py. You could also install it by brew or easy_install(I heard it will be deprecated)

I tried uninstalling gitpython in an attempt to fix the issue, I thought that it would just be reinstalled since its a dependency however I still get the same issue.
Consider upgrading pip version. This should solve the issue

I followed following Github issue thread but din't find any luck.
Could any body tell whats went wrong ?
Thanks
Turns out that there was existing venv-nerapi . Deleting existing virtual env and re-creating it worked fine.

I got a similar issue while using virtual environment. Explicitly mention pip2, this might work
pip2 install misaka
and while executing also mention python2
python2 example.py
I am solved it by take this way:
install conda with prombt of conda install : conda install libpython m2w64-toolchain -c msys2
upgrade your pip by : python -m pip install --upgrade pip
instal misaka : pip install misaka

Next I searched on the last line of the error and followed some suggestions that said to make sure setuptools and ez_install were installed and up to date, but that didn't help.
Then I followed the backup instructions on ReadtheDocs that said to try to install it this way:

cd twython

It turns out that Twython cannot work with Python v3.2 because it depends on the requests module which apparently is not supported in Python 3.2.
One of the developers of Twython just explained this to me on Twitter.
