cython - 摆脱pyximport

我正在尝试使用Cython。我使用setup.py并进行构建，而不是让pyximport做到这一点。但是，每次导入模块时，似乎都会调用pyximport。 Pyximport无法生成，一切都崩溃了。

我用Spyder。我在项目中没有对pyximport的单一引用，但是Spyder似乎并不在乎，并且一直在调用pyximprot。

我从命令窗口(在Spyder外部)调用了程序，并且运行得很好。

如何摆脱对pyximport的调用？还是发生了其他事情？

最佳答案

该问题出现在Spyder中，因为程序包的初始化实际上是在文件utils/site/sitecustomize.py中加载pyximport并调用pyximport.install()。

其他人在GitHub上对此有所提示:

spyder issue #5299

spyder issue #5087

一个不完善的解决方案(例如，将无法在spyder的更新中幸免)，但应该起作用的解决方案是在您的spyder安装中手动编辑sitecustomize.py文件，并删除if HAS_PYXIMPORT:下的部分。
