似乎是更新过一次pip，再安装就这样报错了，删掉注释后已经恢复正常。

一、问题现象

报错信息如下：

Traceback (most recent call last):
  File "/user_name/anaconda3/bin/pip", line 11, in <module>
    sys.exit(main())
             ^^^^^^
  File "/user_name/anaconda3/lib/python3.11/site-packages/pip/_internal/cli/main.py", line 79, in main
    return command.main(cmd_args)
           ^^^^^^^^^^^^^^^^^^^^^^

              ^^^^^^^^^^^
  File "/user_name/anaconda3/lib/python3.11/site-packages/pip/_internal/network/session.py", line 398, in __init__
    self.add_trusted_host(host, suppress_logging=True)
  File "/user_name/anaconda3/lib/python3.11/site-packages/pip/_internal/network/session.py", line 424, in add_trusted_host
    raise ValueError(f"Trusted host URL must include a host part: {host!r}")
ValueError: Trusted host URL must include a host part: '#'

二、问题原因

vi ~/.pip/pip.conf

  1 [global]
  2 index-url = https://pypi.tuna.tsinghua.edu.cn/simple
  3 [install]
  4 trusted-host = https://pypi.tuna.tsinghua.edu.cn  # trusted-host 此参数是为了避免麻烦，否则使用的

主要原因是第 4 行后面的注释内容导致的

三、解决问题

把 ~/.pip/pip.conf 改成下面这样即可

  1 [global]
  2 index-url = https://pypi.tuna.tsinghua.edu.cn/simple
  3 [install]
  4 trusted-host = https://pypi.tuna.tsinghua.edu.cn
