Webpack

Question

我是 webpack 的新手，我似乎无法将其配置为生成源映射。这是我的 webpack.config.js 文件：

var webpack = require("webpack");
var path = require("path");

module.exports = {
    devTool: "#source-map",
    debug: true,
    entry: ['webpack-dev-server/client?http://127.0.0.1:8080/',
        'webpack/hot/only-dev-server',
        './src'
    ],
    devServer: {
        inline: true,
        port:8080
    },
    output: {
        path: path.join(__dirname, 'public'),
        filename: 'bundle.js'
    },
    resolve: {
        moduleDirectories: ['../node_modules', 'src'],
        extensions: ['', '.js']
    },
    module: {
        loaders: [
            {
                test: /\.jsx?$/,
                exclude: /node_modules/,
                loaders: ['react-hot', 'babel?presets[]=react,presets[]=es2015']
            }
        ]
    },
    plugins: [
        new webpack.HotModuleReplacementPlugin()
    ]
};

我试过将 devTool 设置为 "eval-source-map"、"inline-source-map" 等，但没有成功。

Chrome 开发工具未显示任何源地图：

我的package.json:

{
  "name": "rcj-app",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack-dev-server"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "express": "^4.14.0",
    "lodash": "^4.2.1",
    "react": "^0.14.7",
    "react-dom": "^0.14.7"
  },
  "devDependencies": {
    "babel": "^6.5.2",
    "babel-core": "^6.17.0",
    "babel-loader": "^6.2.2",
    "babel-preset-es2015": "^6.3.13",
    "babel-preset-react": "^6.3.13",
    "react-hot-loader": "^1.3.0",
    "webpack": "^1.13.3",
    "webpack-dev-server": "^1.16.2"
  }
}

webpack 配置参数拼写为devtool，而不是devTool。

所以devTool: "#source-map"应该是devtool: "#source-map"。

Webpack - 源地图不工作

Webpack - Source Maps not working
