Webpack捆绑文件未生成

Kri*_*hna 6 javascript reactjs webpack webpack-dev-server

我刚接触webpack并做出反应,只是通过文档并创建了一个工作示例.不幸的是我卡住了,无法继续.问题是没有生成捆绑文件.我创建的文件是

的package.json

{
  "name": "rohith",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack-dev-server"

    "react-dom": "^15.4.1",

我得到的捆绑包有效,但没有生成index.js.无法在localhost 3333中运行

我认为问题在于你没有给出绝对输出路径.

试试这个:

var path = require('path');

module.exports = {
    entry : './main.js',
    output : {
        path : path.join(__dirname, './'),
        filename : 'index.js'
    },
    devServer : {
        inline : true,
        port : 3333
    },
    module : {
        loaders : [
            {
                test : /\.js$/,
                exclude : /node_modules/,
                loader : 'babel',
                query : {
                    presets : ['es2015','react']
                }
            }
        ]
    }
}

在 webpack.config.js 中，使用module.exports代替module.export. 请参阅输出文件名未配置错误在 Webpack 中还要注意，您package.json缺少一些依赖项。这是有效的更新package.json：

{
"name": "rohith",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
  "start": "webpack-dev-server"
},
"author": "",
"license": "ISC",
"dependencies": {
  "react": "^15.4.1",
  "react-dom": "^15.4.1",
  "webpack": "^1.13.3",
  "webpack-dev-server": "^1.16.2"
},
"devDependencies": {
  "babel": "^6.5.2",
  "babel-core": "^6.18.2",
  "babel-loader": "^6.2.8",
  "babel-preset-es2015": "^6.18.0",
  "babel-preset-react": "^6.16.0"
}

将脚本对象替换为以下内容：

"scripts": {
    "start": "npm run build",
    "build": "webpack -p && webpack-dev-server"
  },
