When I installed the sitemap generator I got an exception due to outdated packages.
Traceback
File “/local/lib/python2.7/site-packages/bs4/builder/_html5lib.py”, line 70, in <module>
class TreeBuilderForHtml5lib(html5lib.treebuilders._base.TreeBuilder):
AttributeError: ‘module’ object has no attribute ‘_base’
Fix: We just need to upgrade the packages pip install –upgrade beautifulsoup4 pip install –upgrade html5lib
