强制使用-f(或--force(重建/重新生成细胞化文件，即：
python setup.py build_ext -i -f
或者如果使用pip:
pip install --global-option build --global-option --force .
大致可以理解为：在安装之前，使用选项`--force`运行build(包括build_ext(。
当前的问题是，Cython生成的c/cpp文件将来可能与新的Python版本不兼容。
一个例子是，Cython0.27不支持Python3.8，因为当时Python38还不存在。因此，使用Cython 0.27创建的c/cpp文件(例如git存储库中的cyfusion.cpp(不会使用Py3.8+-headers构建
distutils使用时间戳来决定是否应该重建/重新生成/重新同步文件，就其而言，Cython生成的cyfusion.cpp文件是最新的，因为cyfusion.pyx在生成后没有更改。完全没有考虑Python/Cython版本的业务。
因此，强制distutils重新生成所有内容可以解决过时的c/cpp文件的问题。
一般来说，我不认为将cython生成的文件放入分发/git是一个好主意，因为它可能/将成为未来的绊脚石，有一些例子：
- "tp_print不是_typeobject的成员""-Python3.9+的错误(例如本帖(
- 较旧的cython版本没有属性
__reduce_cython__(例如本帖(
另一个可能的修复方法是从distribution/git存储库中删除过时的(cython生成的(cyfusion.cpp文件并运行
python setup.py build_ext -i
之后。
我的问题由更改
python setup.py build_ext --inplace
至
python setup.py build_ext --inplace -force
