Webpack:ES6语法使模块构建失败:SyntaxError:意外的令牌

Question

我正在尝试使用fixed-data-table的示例,并将其与webpack捆绑在一起.

我正在使用babel-loader和我的代码,否则捆绑没有问题.

webpack根据我的知识运行指向错误的是ES6语法(不是ES5)的一部分... ...,例如:

render() { var {sortDir, children, ...props} = this.props;

在...props具体.

这是我的webpack配置:

"use strict";

var webpack = require("webpack");

module.exports = {
    entry: {
        app: './app.js',
        vendor: ["fixed-data-table","react","react-dom","jquery", "bootstrap", "vis", "chart.js"],
    },
    output: { path: "./", filename: 'bundle.js' },

    plugins: [
        new webpack.optimize.CommonsChunkPlugin(/* chunkName= */"vendor", /* filename= */"vendor.bundle.js"),
        new webpack.ProvidePlugin({
            $: "jquery",
            jQuery: "jquery"
        })
    ],

    module: {
        loaders: [
            {
                test: /.js?$/,
                loader: 'babel-loader',
                exclude: /node_modules/,
                query: {
                    presets: ['es2015', 'react']
                }
            }
        ]
    },
};

我正在使用es2015并作为预设反应并加载babel-loader.为什么它应该理解和处理ES6语法时会抛出语法错误？

这是我的Package.json.我是否需要升级某些版本？

{
  "name": "test",
  "version": "1.0.0",
  "main": "main.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-core": "^6.3.17",
    "babel-loader": "^6.2.0",
    "babel-preset-es2015": "^6.3.13",
    "babel-preset-react": "^6.3.13",
    "babel-runtime": "^6.3.19",
    "webpack": "^1.12.9"
  },
  "dependencies": {
    "bootstrap": "^3.3.7",
    "chart.js": "^2.4.0",
    "fixed-data-table": "^0.6.0",
    "jquery": "^3.1.0",
    "react": "^0.14.3",
    "react-dom": "^0.14.3",
    "vis": "^4.17.0"
  },
  "description": ""
}

我需要将babel预设向后兼容ES7.

解决方法:

npm install babel-preset-stage-0 --save-dev

然后在上面的webpack配置中添加预设:

presets: ['es2015', 'react', 'stage-0']
