网上说是因为某个模块的compileSdkVerion版本高于support的版本，就会报这个错，我把高于27.1.1的，修改低于27.1.1依然报错

问题已解决，我升级了gradle为3.4.1后解决了这个问题，虽然后来还是遇到很多问题，但是发现都离不开第三方的包，找出那个包，基本上都是修改build.gradle里的依赖的版本，play.services.gcm这个我在依赖里碰到了两次，修改版本为15.0.1，找不到资源的问题迎刃而解，至此两个二开项目build在ios和android终跑通，附上遇到的问题的记录，https://blog.csdn.net/qq_39702364/article/details/93484680
