ModuleNotFoundError:即使在安装和重新安装之后，也没有名为“bs4”的模块

Question

我正在运行我的Python文件。(py name.py)

    from bs4 import BeautifulSoup as BS
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python37\lib\site-packages\bs4\__init__.py", line 29, in <module>
    from .builder import builder_registry
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python37\lib\site-packages\bs4\builder\__init__.py", line 294, in <module>
    from . import _htmlparser
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python37\lib\site-packages\bs4\builder\_htmlparser.py", line 7, in <module>
    from html.parser import (
ImportError: cannot import name 'HTMLParseError' from 'html.parser' (C:\Users\Administrator\AppData\Local\Programs\Python\Python37\lib\html\parser.py)

我使用"pip“安装了这个库。库完全删除并再次安装后，运行此代码时会出现此错误。

  File "name.py", line 9, in <module>
from bs4 import BeautifulSoup as BS
ModuleNotFoundError: No module named 'bs4'

Answer 1

我解决了问题。首先，我从我的电脑中删除了所有提到BS4的内容。然后在CMD移动到路径上：

C:\Users\Administrator\AppData\Local\Programs\Python\Python37\Scripts。

在那里度过了命令：

pip install beautifulsoup4
