【bug】使用Nuitka打包基于OCC库软件报错 ImportError: numpy._core.multiarray failed to import 解决方法-优快云博客

问题描述

在使用Nuitka打包基于PythonOCC（OCC）库的软件时，虽然成功生成了exe文件，但在运行时遇到了numpy导入错误。
报错信息如下

解决方法

将虚拟环境中numpy版本降级到1.25.2，可解决这个问题。

pip install numpy==1.25.2

后续在使用这个命令进行打包，最后成功运行exe文件。（注意调整自己需要的plugin和package）

nuitka --onefile --standalone ^
--enable-plugin=pyqt5 ^
--include-package=numpy ^
--include-package-data=numpy ^
main.py
