同学你好： 建议同学换一下国内的镜像源。 先升级一下pip 命令 python -m pip install --upgrade pip 然后 例如：pip install pygame -i xxxxxxxxxxxxxxxxxxx 清华：https://pypi.tuna.tsinghua.edu.cn/simple 阿里云：http://mirrors.aliyun.com/pypi/simple/ 中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/ 华中理工大学：http://pypi.hustunique.com/ 山东理工大学：http://pypi.sdutlinux.org/ 豆瓣：http://pypi.douban.com/simple/

You are using pip version 10.0.1, however version 20.0.2 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command. 老师，还是报错，是我的pip没更新成功吗？
