报错1如下：

直接看最后一行：

超时了，我连接的是自家的wife，所以可能慢点，不够用，所以我换了一个网络，开启手机热点再试一次：

C:\Users\Administrator>pip install pygame

成功！

报错2如下：

(venv) D:\PyCharm\PlaneDemo>pip install pygame
Requirement already satisfied: pygame in d:\pycharm\planedemo\venv\lib\site-packages (2.0.1)
WARNING: You are using pip version 20.2.3; however, version 21.0 is available.
You should consider upgrading via the 'd:\pycharm\planedemo\venv\scripts\python.exe -m pip install --upgrade pip' command.

解决方法：（参考来自博主：翰誉华风）

首先输入命令：

python -m pip install --upgrade pip -i https://pypi.douban.com/simple

再输入命令：

pip install pygame
