1.如上图所示：没有任何语法错误，可是只要加上</button>闭合标签后就乱套了
解决方案：sublimetext view-syntax-babel-javascript(babel)将语法格式改为javascript(babel)即可
2.requires Babel "7.0.0-0",but was loaded with "6.26.0".If you are sure you have a compatible version of @babel/core,it is likely...
解决方案：安装babel7.0 npm i -D babel-core@^7.0.0-bridge.0 一定要有后面的-bridge.0 不然会报错
