node.js - webpack 配置文件 运行出错

Question

项目目录

webpack.config.js

// nodejs 中的path模块
var path = require('path');

module.exports = {
    // 入口文件，path.resolve()方法，可以结合我们给定的两个参数最后生成绝对路径，最终指向的就是我们的index.js文件
    entry: path.resolve(__dirname, '../app/index/index.js'),
    // 输出配置
    output: {
        // 输出路径是 myProject/output/static
        path: path.resolve(__dirname, '../output/static'),
        publicPath: 'static/',
        filename: '[name].[hash].js',
        chunkFilename: '[id].[chunkhash].js'
    },
    resolve: {
        extensions: ['', '.js', '.vue']
    },
    module: {

        loaders: [
            // 使用vue-loader 加载 .vue 结尾的文件
            {
                test: /\.vue$/,
                loader: 'vue'
            },
            {
                test: /\.js$/,
                loader: 'babel?presets=es2015',
                exclude: /node_modules/
            }
        ]
    }
}

index.js

import Vue from 'Vue'
import Favlist from '../components/Favlist' 
new Vue({
    el: 'body',
    components: {
        Favlist
    }
})

错误

请教大神 刚学习 vue想搭个项目跑一跑结果就这样

Answer 1

The last line of the error message already tells you,

resolve: {
    extensions: ['', '.js', '.vue']
},

The first element cannot be ‘’, put it at the last position

Answer 2

Configuration.resolve.extension[0] Doesn’t it correspond to the first value in the array of your extensions: ['', '.js', '.vue']?
Follow the prompts, it cannot be empty here.
