运行pyside2报错This application failed to start because no Qt platform plugin could be initialized.

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

加入这几行代码就ok啦，可以跳出来自己设计的界面了。
