Question

我正在尝试使用Cython。我使用setup.py和build而不是让pyximport这样做。但是，每次导入我的模块时，都会调用pyximport。 Pyximport无法构建，一切都崩溃了。

我使用Spyder。在我的项目中我没有对pyximport的单一引用，但是Spyder似乎并不关心并且一直在调用pyximprot。

我从命令窗口（Spyder外部）调用了我的程序，它运行得很好。

我如何摆脱对pyximport的调用？或者还有其他事情发生了吗？

Answer 1

问题出现在Spyder中，因为软件包的初始化实际上会在文件utils/site/sitecustomize.py中加载pyximport并调用pyximport.install()。

其他人在GitHub上抱怨过：

一个不优雅的解决方案（例如，在spyder更新后无法生存）但是应该可以在你的spyder安装中手动编辑sitecustomize.py文件并删除if HAS_PYXIMPORT:下的部分
