error - typescript - Cannot find name 'Set'

1. 在react & Webpack中集成typescript出現如下問題

• 在react & Webpack中集成typescript編譯的時候出現如下錯誤:

  ERROR in [at-loader] ./node_modules/@types/react/index.d.ts:427:23 
      TS2583: Cannot find name 'Set'. Do you need to change your target library? Try changing the `lib` compiler option to es2015
  or later.
  

2. 錯誤原因

• tsconfig.json裏面的配置 compilerOptions.target這個js版本寫的過低，所以不支持set

3. 解決方案

• tsconfig.json裏面的配置改成 compilerOptions.target = 'es6'

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