RequestsDependencyWarning: urllib3 (2.0.0.dev0) or chardet (3.0.4) doesn't match a supported version!   RequestsDependencyWarning)

用requests模块爬虫时出现这个警告，意思urllib3模块和chardet模块俩个不一致，支持不太好，所以需要将这俩个卸载，然后，将requests模块更新，或者将requests模块卸载重新安装即可：

  1. pip uninstall urllib3
  2. pip uninstall chardet
  3. pip install --upgrade requests
