pip install pyminifier

执行上面的命令会报错：

根据网上博客提供的教程，这时候再安装一个2to3的库

pip install 2to3

然后再执行pip install pyminifier还是一样的报错信息，后来经过排查找到一个pyminifier3库，Pyminifier3是由社区维护的一个分支，专门用于Python 3的代码混淆和压缩。
pypi地址：https://pypi.org/project/pyminifier3/
github地址：https://github.com/dzhuang/pyminifier3
Python3安装命令：

pip install pyminifier3

输出结果：
