error - typescript - Cannot find name Set

ERROR  in  [at-loader] ./node_modules/@types/react/index.d.ts: 377 : 23   
    TS2583: Cannot find name   '  Set  ' . Do you need to change your target library? Try changing the `lib` compiler option to es2015 or later.

错误原因：tsconfig.json里面的配置 compilerOptions.target这个js版本写的过低，所以不支持set

修改方法：tsconfig.json里面的配置改成 compilerOptions.target = 'es6'

 {
     "compilerOptions" : {
         "outDir": "./dist/" ,
         "sourceMap":  true  ,
         "noImplicitAny":  true  ,
         "module": "commonjs" ,
         "target": "es6" ,
         "jsx": "react" 
    },
     "include" : [
         "./src/**/*" 
    ],
     "exclude" : [
         "node_modules" ,
         "**/*.spec.ts" 
    ]
}
