pip 不会安装或下载

Question

pip 没有安装任何东西，而是反复给我一个错误，然后告诉我升级 pip，当我尝试升级 pip 时，它显示相同的错误

我尝试了不同版本的python，它们都显示相同的错误

You are using pip version 19.0.3, however version 19.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

我只想安装 pygame，但它不会让我安装。

试试这个命令：

pip install --upgrade pip --trusted-host pypi.org --trusted-host files.pythonhosted.org
