html5lib 中的故障？

Question

我收到这个错误。 是错误还是代码错误？ 这是什么意思？

Traceback (most recent call last):
  File "isc.py", line 8, in <module>
    import requests, os, sys, bs4
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/bs4/__init__.py", line 30, in <module>
    from .builder import builder_registry, ParserRejectedMarkup
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/bs4/builder/__init__.py", line 314, in <module>
    from . import _html5lib
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/bs4/builder/_html5lib.py", line 70, in <module>
    class TreeBuilderForHtml5lib(html5lib.treebuilders._base.TreeBuilder):
AttributeError: module 'html5lib.treebuilders' has no attribute '_base'

（我升级了 html5lib bs4 和请求）

这是与您的 html5lib package 版本有关的问题，请尝试升级它。
