删除了C:\Users\24033\AppData\Local\UnrealEngine\Common 目录下的全部内容，然后找到引擎的安装目录BaseEngine.ini文件用记事本打开它，然后搜索InstalledDerivedDataBackendGraph并找到%ENGINEVERSIONAGNOSTICUSERDIR%DerivedDataCache把它改为%GAMEDIR%DerivedDataCache，但是打开工程，完成着色器编译之后，关闭，之后再打开，还要重新编译着色器。 Delete all the contents in the C:\Users\24033\AppData\Local\UnrealEngine\Common directory, then find the BaseEngine.ini file of the engine installation directory and open it with Notepad, then search InstalledDerivedDataBackendGraph and find %ENGINEVERSIONAGNOSTICUSERDIR%DerivedDataCache to change it It is %GAMEDIR%DerivedDataCache, but after opening the project and completing the shader compilation, close it, then open it again, and you need to recompile the shader.
