我是编程和 Python 的新手。我正在尝试在 Python3 上安装 BeutifulSoup 来学习 MOOC 的网络抓取（使用 Jupyter Notebooks 作为 IDE）。当我运行时，from bs4 import BeautifulSoup我收到以下错误
AttributeError Traceback (last last call last) in 3 import ssl 4 print("done2") ----> 5 from bs4 import BeautifulSoup 6 print("done3")
~\Desktop\py4e\code3\code3\bs4__init__.py in 28 import warnings 29 ---> 30 from .builder import builder_registry, ParserRejectedMarkup 31 from .dammit import UnicodeDammit 32 from .element import (

AttributeError：模块“html5lib.treebuilders”没有属性“_base”
我尝试了以下解决方案：
1) pip install html5lib==0.9999999
2) pip install --upgrade html5lib==1.0b8
3) pip install --upgrade bleach==1.4.2
3) 更新 BeutifulSoup (pip install) 4) 降级后重新安装 html5lib 到最新版本不起作用
非常感谢您的帮助！
