解决PySide2的This application failed to start because no Qt platform plugin could be initialized问题

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”
