关于python3.6导入bs4时不起作用

Question

我将bs4导入为：

from bs4 import BeautifulSoup

但它会引发如下错误：

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]

但它在python2.7中有效。 我将bs4更新为：

pip install --upgrade beautifulsoup4

它还行不通。

怎么解决这个问题，谢谢〜！

您应该升级您的beautifulsoup模块，使其与python 3.6兼容。 从4.4.0开始， BeautifulSoup与Python 3.5兼容。 以上

pip3 install --upgrade beautifulsoup4
