Hello mazhentao, thank you both for posting and welcome to the Unreal community.
This error is a interesting. Would you mind letting me know if your project has any plugins you enabled yourself. I am asking because it is possible a plugin may need you to recompile your project or even generate VS project files. There are also a few more causes on the link I will provide shortly.
Here is a relevant thread on this subject with a few great solutions.
I hope this helps.
