babel-preset-env SyntaxError：带箭头函数的意外标记

Question

为什么 babel-preset-env 不接受箭头功能？

.babelrc configuration reference

{
    "presets": [
        "react",
        [
            "env",
            {
                "targets": {
                    "browsers": [
                        "last 2 versions",
                        "safari >= 7"
                    ]
                },
                "debug": true,
                "modules": "commonjs",
                "include": [
                    "transform-es2015-arrow-functions",
                    "es6.map"
                ],
                "exclude": [
                    "transform-regenerator",
                    "es6.set"
                ]
            }
        ]
    ],
    "plugins": [
        "transform-es2015-destructuring",
        "transform-object-rest-spread"
    ]
}

的package.json

{
  "name": "myapp",
  "version": "0.1.0",
  "main": "index.js",
  "private": true,
  "dependencies": {
    "babel-core": "6.25.0",
    "babel-loader": "7.1.1",
    "babel-preset-env": "^1.6.0",
    "babel-preset-react": "^6.24.1",
    "css-loader": "0.28.4",
    "file-loader": "0.11.2",
    "react": "^15.6.1",
    "react-datepicker": "^0.52.0",
    "react-dom": "^15.6.1",
    "react-redux": "^5.0.6",
    "react-router": "^4.1.2",
    "react-router-dom": "^4.1.2",
    "webpack": "3.5.1",
    "webpack-dev-server": "2.7.1",
    "webpack-node-externals": "^1.6.0"
  },
  "scripts": {
    "build": "webpack"
  },
  "devDependencies": {
    "babel-plugin-transform-es2015-destructuring": "^6.23.0",
    "babel-plugin-transform-object-rest-spread": "^6.26.0"
  }
}

  

答案：完全正常工作.babelrc

{
    "presets": [
        "react",
        [
            "env",
            {
                "targets": {
                    "browsers": [
                        "last 2 versions",
                        "safari >= 7"
                    ]
                },
                "debug": true,
                "modules": "commonjs"
            }
        ]
    ],
    "plugins": [
        "transform-object-rest-spread",
        "transform-class-properties"
    ]
}
