If you do not have Cython installed then use: pip install Cython.
However, if you do have an old version of Cython installed like me then this is what solved it for me: pip install --upgrade Cython
如果您没有安装 Cython，请使用：pip install Cython. 但是，如果您确实像我一样安装了旧版本的 Cython，那么这就是为我解决的问题：pip install --upgrade Cython
