错误：“PyThreadState”{aka“struct _ts”}没有名为“exc_type”的成员；您的意思是“curexc_type”吗？构建 Cython 扩展时

Question

我在 Python 3.8 中收到以下错误，而在 Python 3.6 中则没有收到该错误。我怎样才能让它与Python 3.8一起工作？为了重现该错误，请按照此处操作： https: //github.com/davidstutz/mesh-fusion/issues/7

Answer 1

-f使用(或)强制重建/重新生成 cythonized 文件--force，即：

\n

python setup.py build_ext -i -f\n

\n

或者如果使用pip：

\n

pip install --global-option build --global-option --force .\n

\n

可以粗略地解释为：在安装运行build（包括build_ext）之前使用选项 \xc2\xb4--force`。

\n\n

目前的问题是，Cython 生成的 c/cpp 文件将来可能与新的 Python 版本不兼容。

\n

一个例子是，Cython 0.27 不支持 Python3.8，因为当时 Python3.8 还不存在。因此，使用 Cython 0.27 创建的 c/cpp 文件（例如cyfusion.cpp来自 git-repository）将无法使用 Py3.8+-headers 构建。

\n

distutils使用时间戳来决定文件是否应该重建/重新生成/回收，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。根本没有考虑整个不同的 Python/Cython 版本业务。

\n

因此，强制 distutils 重建所有内容可以解决过时的 c/cpp 文件的问题。

\n

一般来说，我认为将 cython 生成的文件放入 distribution/git 中不是一个好主意，因为它可能/将成为将来的绊脚石，有一些这样的例子：

\n

\n
• “\xe2\x80\x9ctp_print 不是 _typeobject\xe2\x80\x9d”的成员 - Python3.9+ 的错误（例如这篇文章）
\n
• 旧的 cython 版本没有属性__reduce_cython__（例如这篇文章）
\n

\n\n

另一个可能的修复方法是从 distribution/git-repository 中删除过时的（cython 生成的）cyfusion.cpp文件并运行

\n

python setup.py build_ext -i\n

\n

然后。
