node.js - webpack的 extract text plugin for webpack 报错怎么回事？

Question

官方的例子，都跑不起来？

const ExtractTextPlugin = require("extract-text-webpack-plugin");
module.exports = {
    entry: "./src/js/app.js",
    output: {
        path: __dirname,
        filename: "bundle.js"
    },
    module: {
        loaders: [
            { test: /\.css$/, loader: ExtractTextPlugin.extract("style-loader", "css-loader") },
            { test: /\.styl$/, loader: ExtractTextPlugin.extract("style-loader", "css-loader","stylus-loader") },
            { test: /\.js$/, exclude: /node_modules/, loader: "babel-loader" }
        ]
    },
    plugins: [
        new ExtractTextPlugin("styles.css")
    ]
};

错误信息：

Answer 1

你看下你的node_modules下有没有webpack/lib/removeAndDo.js这个文件

没有的话，就npm install 或者直接把node_modules下全部删除，然后重新安装一下试试

Answer 2

你需要参考一下 webpack 的 travis 配置，之前是需要强行 npm link webpack 的，但现在使用yarn就不用了

Answer 3

npm remove webpack -g
npm i webpack -D

Answer 4

Run npm install in the root of the project.
Run npm link webpack in the root of the project.
Run node build.js in the specific example directory. (Ex: cd examples/commonjs && node build.js)

example下的README里有
