Question

在我的webpack.config.js文件中：

const webpack = require('webpack');
const fs = require('fs');
const path = require('path'),


join = path.join,
resolve = path.resolve;


const root = resolve(__dirname);
const src = join(root, 'src');
const modules = join(root, 'node_modules');
const dest = join(root, 'dist');

const NODE_ENV = process.env.NODE_ENV;
const isDev = NODE_ENV === 'development';

const getConfig = require('hjs-webpack');
var config = getConfig({
    isDev: isDev,
    in: join(src, 'app.js'),// entry point file
    out: dest,
    // blow away any previously built files before it starts building new ones
    clearBeforeBuild: true
    });


config.module.loaders.push({
    test: /\.css$/,
    include: [modules],
    loader: 'style!css'
  })


module.exports = config;

运行开发人员时。服务我得到以下错误：

Failed to load webpack config, please use like this
hjs-dev-server.js webpack.config.js

原来 config.module.loaders返回null ，我在这里到底在做什么错，我从没使用过“ hjs-webpack”，感谢任何帮助

Answer 1

Cannot read property 'push' of undefined提示config.module.loaders未定义。

这是一个webpack配置，在webpack配置中，加载程序位于module.rules中，我认为module.loaders无法识别（并且因此，getConfig可能不会返回。）

我建议您尝试将modules替换为rules，如下所示：

    config.module.rules.push({
        test: /\.css$/,
        include: [modules],
        loader: 'style!css'
    });

Answer 2

WP加载器驻留在rules子数组中。

此外-对hjs-webpack中的导出进行的快速检查显示，实际上loaders对象上没有module属性。

因此-您应按以下方式更新代码：

config.module.loaders.push({
test: /\.css$/,
include: [modules],
loader: 'style!css'})
