根本原因:最新的vue-loader 15+以上,要求使用vueloaderplugin,需要变更webpack配置文件
一、报错代码:
ERROR in ./src/login.vue?vue&type=template&id=19e76240& 2:0 Module parse failed: Unexpected token (2:0) File was processed with these loaders: * ./node_modules/vue-loader/lib/index.js You may need an additional loader to handle the result of these loaders. | > <h1>这是使用.vue文件渲染出来的</h1> | | @ ./src/login.vue 1:0-84 10:2-8 11:2-17 30:4-35:6 30:68-35:5 32:16-22 33:25-40 @ ./src/main.js
二、解决办法:
const path = require('path'); const htmlWebpackplugin = require('html-webpack-plugin'); const VueLoaderPlugin = require('vue-loader/lib/plugin'); module.exports = { entry: path.join(__dirname,'./src/main.js'), output: { path: path.join(__dirname, './dist'), filename: 'bundle.js' }, plugins: [ new htmlWebpackplugin({ //创建一个在内存中生成的html页面的插件 template: path.join(__dirname, './src/index.html'), filename: 'index.html' }), new VueLoaderPlugin() ], module: { //这个节点用于配置所有的第三方模块加载器 rules: [ {test: /.css$/, use:['style-loader','css-loader']},//配置处理.css文件的第三方处理规则 {test: /.less$/, use: ["style-loader",'css-loader','less-loader']}, {test: /.scss$/, use: ["style-loader",'css-loader','sass-loader']}, {test: /.(jpg|png|gif|bmp|jpeg)$/, use: "url-loader?limit=8000"}, {test: /.(tff|eot|svg|woff|woff2)$/, use: "url-loader"}, {test:/.js$/, use:'babel-loader',exclude:/node_modules/}, {test: /.vue$/, use: 'vue-loader'} ] } };
1.需要配置{test: /.vue$/, use: 'vue-loader'}
2.还需要载webpack.config.js配置文件中加两行代码:
const VueLoaderPlugin = require('vue-loader/lib/plugin');
new VueLoaderPlugin()
三、补充出错原因
- vue-loader@15.*之后 必须配置带有VueLoaderPlugin 之外,还需另外单独配置css-loader。
- 如果是用最新webpack原生构建,除了安装webpack外,还要安装webpck-cli,在webpack.config中配置mode选项
- 为保持构建环境一致,请采用`npm run dev`脚本编译的形式,以确保使用的webpack命令,vue-loader是本地版本。
