PySide报错:This application failed to start because not Qt platform plugin could be initialized

描述错误

启动 pyside2 程序,报错如下:

This application failed to start because not Qt platform plugin could be initialized.Reinstalling the application may fix this problem.

解决方式一

在程序初始部分添加如下代码:

dirname = os.path.dirname(PySide2.__file__)
plugin_path = os.path.join(dirname, 'plugins', 'platforms')
os.environ['QT_QPA_PLATFORM_PLUGIN_PATH'] = plugin_path
注意

使用这种方式,可能失去windows10样式,是windows早期的版本,可增加下面代码,启用 Fusion 样式,各个平台一致的UI界面:

QApplication.setStyle("Fusion")

其他方式
