python - 为什么在使用 pyinstaller 构建 .exe 时出现 ImportError？

Question

我刚刚创建了一个小的 GUI 程序，它可以在 IPython 中编译并正常工作，但是当我尝试使用 pyinstaller 将它导出到 .exe 时，它给我一个导入错误。我确定它是 sklearn，因为当我注释掉 sklearn 导入时，我的文件在构建时可以正常打开。

您仍然可以通过在命令中添加以下内容来使用 pyinstaller:

--hidden-import sklearn.neighbors.typedefs

或将以下内容添加到您的 .spec 文件中:

hiddenimports=['cython', 'sklearn', 'sklearn.neighbors.typedefs']
