学习使用PySide2，按照官网说明，一步一步做，报错“This application failed to start because no Qt platform plugin could be initialized“。使用pyinstaller发布后，提示“This application failed to start because no Qt platform plugin could be initializedAvailable platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc, xcb"。

解决办法

1.在代码中加入如下代码即可（如果这步不行，可以尝试第2步）

import sys,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
print(plugin_path)

2.将路径“D:\ProgramData\Anaconda3\Lib\site-packages\PySide2\plugins\platforms”下的五个dll复制到“
D:\ProgramData\Anaconda3\Library\plugins\platforms”
