cython - 摆脱 pyximport

Question

我正在尝试使用 Cython。我使用 setup.py 并构建，而不是让 pyximport 执行此操作。但是，每次我导入模块时，似乎都会调用 pyximport 。 Pyximport 构建失败，一切都崩溃了。

我使用 Spyder。我的项目中没有对 pyximport 的单个引用，但 Spyder 似乎并不关心并不断调用 pyximprot。

我从命令窗口(Spyder 之外)调用了我的程序，它运行得很好。

如何摆脱对 pyximport 的调用？还是发生了其他事情？

该问题出现在 Spyder 中，因为该包的初始化实际上加载了 pyximport 并调用了文件 utils/site/sitecustomize.py 中的 pyximport.install()。 .

其他人在 GitHub 上对此提出了提示:

• spyder issue #5299
• spyder issue #5087

一个不太优雅的解决方案(例如，无法在 spy 程序的更新中幸存)但应该有效的解决方案是手动编辑 spy 程序安装中的 sitecustomize.py 文件，并删除 if HAS_PYXIMPORT:
