beautifulsoup, html5lib: module object has no attribute _base

When I updated my packages I have this new error:

class TreeBuilderForHtml5lib(html5lib.treebuilders._base.TreeBuilder):
AttributeError: 'module' object has no attribute '_base'

I tried to update beautifulsoup, with no more result. How can I fix that?


I upgraded beautifulsoup4 and html5lib and it resolved the issue.

pip install --upgrade beautifulsoup4
pip install --upgrade html5lib

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


edit nov, 2017: it seems this doesn't work any more

Finally found out, a search engine didn't throw anything but it's referenced on beautifulsoup's issue tracker: https://bugs.launchpad.net/beautifulsoup/+bug/1603299

it works back with html5lib v0.9999999 (7 nines)

"html5lib<=0.9999999"
