python - 导入错误: No module named 'requests.exceptions'

Question

对编码非常陌生，我正在尝试学习 Python。我使用 Anaconda 来管理包等。我通常在 cmd 中使用 conda update conda 或 conda update anaconda

等命令更新 Anaconda/conda

最近，当使用这些命令时，它会出现一条消息:“ImportError:没有名为“Requests.exceptions”的模块”，然后是“导入错误:无法导入名称“Session””，请参见下文。

Traceback (most recent call last):
  File "C:\Program Files\Anaconda3\lib\site-packages\conda\cli\main.py", line 171, in main
    activate.main()

    from requests.exceptions import ConnectionError, HTTPError, InvalidSchema, SSLError
ImportError: No module named 'requests.exceptions'

During handling of the above exception, another exception occurred:

    sys.exit(main())

    from requests import Session, __version__ as REQUESTS_VERSION
ImportError: cannot import name 'Session'

我尝试过使用像pip install requests这样的命令，但它说它已经说“要求已经满足并列出了它的安装位置(我猜测)。

此时，我什至无法从 conda 命令(例如 conda info --envs)获得响应。当我输入该内容时它不会执行任何操作。

如果我需要卸载 conda/anaconda，我会的，但我只是缺少一个简单的修复吗？

谢谢 friend 们!

如果您打算使用 conda 作为 python 环境，则应该使用 conda 安装 requests。
