无法在导入请求时从“集合”导入名称“映射”

Question

Python 版本：Python 3.10.4
PIP 版本：pip 22.0.4

所以我试图用套接字制作一个小项目，我添加了一个上传文件的功能，但是每当我导入请求时，它都会抛出此错误。下面是我运行的代码。

Traceback (most recent call last):
  File "C:\Programming\WireUS\test.py", line 1, in <module>
    import requests
  File "C:\Users\John\AppData\Local\Programs\Python\Python310\lib\site-packages\requests\__init__.py", line 43, in <module>
    import urllib3
  File "C:\Users\John\AppData\Local\Programs\Python\Python310\lib\site-packages\urllib3\__init__.py", line 8, in <module>
    from .connectionpool import (

    from .connection import (

    from .util.ssl_ import (

    from .connection import is_connection_dropped
  File "C:\Users\John\AppData\Local\Programs\Python\Python310\lib\site-packages\urllib3\util\connection.py", line 3, in <module>
    from .wait import wait_for_read
  File "C:\Users\John\AppData\Local\Programs\Python\Python310\lib\site-packages\urllib3\util\wait.py", line 1, in <module>
    from .selectors import (
  File "C:\Users\John\AppData\Local\Programs\Python\Python310\lib\site-packages\urllib3\util\selectors.py", line 14, in <module>
    from collections import namedtuple, Mapping
ImportError: cannot import name 'Mapping' from 'collections' (C:\Users\John\AppData\Local\Programs\Python\Python310\lib\collections\__init__.py)

即使这个基本代码也给了我这个错误。

正如user2357112-supports-monica所说，运行pip install urllib3可以修复它。
