Resolve QT compilation dynamic link library could not find or load the QT platform plugin "Windows" in. Issues

Recently used QT5 to do a project interface, in the translation into executable exe, run the file, prompt:

This application failed-to-start because it could not find or load the Qt PLATFO
RM Plugin "Windows"
In "".

Reinstalling the application may fix this problem.

Looked up a lot of information, tried the method, and later found that the D:\Anaconda2\Library\plugins under the platforms folder copied to the project file directory (to copy the entire folder), you can resolve the problem.
