关于启动SingingPianoQt.pyw后无法正常运行的问题

[zxcv-12345]

C:\Users\xxx\Desktop\SingingPiano-master>python SingingpianoQt.pyw zh_CN i18npath:['languages'] qt.qpa.plugin: Could not load the Qt platform plugin "windows" in "" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: direct2d, minimal, offscreen, windows.

运行SingingPianoQt.pyw后出现以上信息如何解决？
