AttributeError: 模块 'PyQt5' 没有属性 '__version__'

Question

我试图将 python 文件转换为 .exe 文件。但是有了这两行，我就遇到了这个问题。

 import cv2
exit()

AttributeError: Module 'PyQt5' has no attribute '__version__'

如果我只是打印类似： print('dsfdsfs') 的内容，那么它可以成功包装为 .exe。

我的环境：

win10

pyinstaller 5.0.dev0

opencv-python 4.5.2.54

pyqt 5.9.2

我正在使用 anaconda prompt 来这样做。

我正在使用 pyinstaller 和 anaconda prompt 并发现了同样的问题，要解决它你必须

pip install PyQt5 --user --use-feature=2020-resolver

然后再次运行 pyinstaller。
