AttributeError: type object 'HTMLAwareEntitySubstitution' has no attribute 'preserve_whitespace_tags' error message when trying to import BeautifulSoup

I am just trying this for the first time.  I installed BeautifulSoup and html5lib.  When I try this command:  from bs4 import BeautifulSoup, I get the following error message:

I found one posting on reddit that said when they installed html5lib, their issue resolved, but mine has not.

Any thoughts?

I am using Python 3.5, Jupyter Notebook IPython version 4.2.0, windows 10

Thank you.

This must be an Anaconda issue.  I opened up the same Jupyter notebook using Canopy, and BeautifulSoup imported without any issues.

Thanks

Any thoughts?  I would like to install this so I can use without having to go to Canopy.

This is an issue with upstream package html5lib: https://bugs.launchpad.net/beautifulsoup/+bug/1603299
To fix, force downgrade to an older version:

pip install --upgrade html5lib==1.0b8
