When I updated my packages I have this new error:
class TreeBuilderForHtml5lib(html5lib.treebuilders._base.TreeBuilder):
AttributeError: \'module\' object ha
This command solved the problem for me:
sudo pip install html5lib==0.9999999
The downgrade to html5lib 1.0b8 in @Bhavuk answer works but courses a version issue with bleach.
The solution for me was with a change of version of bleach to be compatible with the new version of html5lib
pip install --upgrade bs4
pip install --upgrade bleach==1.4.2
pip install --upgrade html5lib==1.0b8
Python version 3.5
