我还不断地一遍又一遍地得到了同样的错误在我的计划，我不能找出如何解决它。 R 1不能被解析到一个错误。我试图建立我的项目，我也没有进口涉及.R？请问有谁知道如何解决它？

I have constantly gotten the same error over and over in my program and i can't find out how to fix it. R cannot be resolved to an error. I have tried to build my project and i have no imports that involve .R? Would anyone know how to fix it?
