python - 关于python3.6当我导入bs4时，它不起作用

Question

我将 bs4 导入为：

from bs4 import BeautifulSoup

但它会引发这样的错误：

Traceback (most recent call last):
  File "/Users/koudai232/Desktop/test.py", line 4, in <module>
    from bs4 import BeautifulSoup
  File "/usr/local/lib/python3.6/site-packages/bs4/__init__.py", line 30, in <module>
    from .builder import builder_registry, ParserRejectedMarkup
  File "/usr/local/lib/python3.6/site-packages/bs4/builder/__init__.py", line 308, in <module>
    from . import _htmlparser
  File "/usr/local/lib/python3.6/site-packages/bs4/builder/_htmlparser.py", line 7, in <module>
    from html.parser import (
ImportError: cannot import name 'HTMLParseError'
[Finished in 0.1s with exit code 1]
[cmd: ['/usr/local/bin/python3', '-u', '/Users/koudai232/Desktop/test.py']]
[dir: /Users/koudai232/Desktop]
[path: /usr/bin:/bin:/usr/sbin:/sbin]

但它适用于python2.7。我将我的 bs4 更新为：

pip install --upgrade beautifulsoup4

它还不行。

这个问题怎么解决，谢谢~！

你应该升级你的 beautifulsoup 模块以适应 python 3.6。从 4.4.0 开始，BeautifulSoup与 Python 3.5 兼容。以上

pip3 install --upgrade beautifulsoup4
