报错内容：

Pycharm报错：

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, webgl,windows.

VSCode报错：

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, webgl, windows.

原因：

anaconde中安装了多个包（Pyside2、Pyside6、PyQt5）引发了冲突。

解决办法：

根据当前程序引用的包修改 anaconda > Library > plugins > platforms 下的dll文件

1.查看当前程序引用的包（我用到了PySide2）:

2.在路径： anaconda > Lib > site-packages > Pyside2(根据你所引用的包) > plugins > platforms 复制这些文件

3.到路径：anaconda > Library > plugins > platforms 把刚才复制的内容粘贴到这里，替换掉原有同名文件

4.程序成功运行
