Could it be a problem with pip and it's vendored html5lib version incompatibility? There is one bug report in pip repo about Anaconda patching pip that seems to cause this error : https://github.com/pypa/pip/issues/4902 .

Can you please share the pip and python version to see if I can reproduce this? Is the pip being used part of the one at 3.6 release?

./venv/bin/pip --version

I am using Python 3.6.4 from homebrew. I can reproduce this is by manually editing ./venv/lib/python3.6/site-packages/pip/_vendor/html5lib/_inputstream.py and removing transport_encoding from HTMLBinaryInputStream's constructor. 

./venv/lib/python3.6/site-packages/pip/_vendor/html5lib/__init__.py contains the version number of html5lib. Mine is 1.0b10. 

Sample error I got similar to the report : 

➜  Doc git:(master) ✗ ./venv/bin/pip install sphinx
