React, Webpack: bundle.js is not generated

本文关键字：is not generated js bundle Webpack React      更新时间：2023-09-26

Edit：原因是我运行的是webpack-dev-server，当只运行webpack时，它起作用了。

我正在使用React和Webpack。不生成bundle.js。我在SO上发现了这个问题，这也带来了同样的问题，但我似乎已经安装了所需的依赖项。这是我的webpack.config.js:

var webpack = require('webpack');    
module.exports = {
    entry: [
        'webpack-dev-server/client?http://localhost:8080',
        'webpack/hot/only-dev-server',
        './src/index.js'
    ],
    module: {
        loaders: [{
            test: /'.js?$/,
            exclude: /node_modules/,
            loader: 'react-hot!babel'
        }]
    },
    resolve: {
        extensions: ['', '.js']
    },
    output: {
        path: 'dist',
        publicPath: '/',
        filename: 'bundle.js'
    },
    devServer: {
        contentBase: './dist',
        hot: true
    },
    plugins: [
        new webpack.HotModuleReplacementPlugin()
    ]
};

这是我的包.json:

{
  "name": "plump",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo '"Error: no test specified'" && exit 1"

  }
}

知道吗？

编辑。运行webpack:时的输出

webpack: bundle is now VALID.

输出路径可能有问题。。您可以尝试替换./dist 的输出路径吗

这是由于package.json的脚本中缺少一些键值对。用以下内容替换您的脚本对象：

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

"-p"表示专门用于webpack.config.js的生产环境。然后运行此cmd:$ npm start

$ npm start将调用npm run build cmd，后者将调用"webpack-p&&webpack-dev server"
