could not find or load the Qt platform plugin "windows in "".解决方法

打开spyder遇到

"This application failed to start because it could not find or load the Qt
platform plugin "windows in "".

Reinstalling the application may fix this problem."

看了网上很多都没有解决

最后通过打开Anaconda Prompt运行conda update qt之后问题得到解决。
