参考了这位博主的帖子：【动手学强化学习】gym 0.18.3 安装教程

setuptools

setuptools是pip自带的包，默认是最新的版本，我原本setuptools的版本是68.2.2 ，直接安装gym0.18.3会报错，需要降版本，参考的版本57.5.0：

pip install --upgrade pip setuptools==57.5.0

wheels

原因同上，我原本wheel的版本是0.41.2，降为0.37.0

pip install --upgrade pip wheel==0.37.0

降完上面两个包的版本即可安装gym==0.18.3

pip install gym==0.18.3

这次没有报原来的错误，开始安装依赖
