Python Pip在安装软件包时给出相同的错误

当我用pip安装软件包时，它总是给出相同的错误，即使软件包不存在。我不能理解这个错误，也没有给我错误代码。我正在安装的软件包称为pyinput

$ pip install pyinput
Collecting pyinput

如果有人能帮我，我将不胜感激。

谢谢。

试试这个，如果这能解决您的问题，请告诉我

pip3 install -trusted-host=pypi.org -trusted-host=python.pypi.org -trusted-host=files.pythonhosted.org pyinput

试一试

重复的？可能重复的编号。我收到一个不同的错误，该错误太长，无法添加注释。我会移动它聊天，但我没有足够的代表做这件事。

pip uninstall pyOpenSSL cryptography

sudo pip install pyOpenSSL cryptography
