根本原因:最新的vue-loader 15+以上,要求使用vueloaderplugin,需要變更webpack配置文件
一、報錯代碼:
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>這是使用.vue文件渲染出來的</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、解決辦法:
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({ //創建一個在內存中生成的html頁面的插件 template: path.join(__dirname, './src/index.html'), filename: 'index.html' }), new VueLoaderPlugin() ], module: { //這個節點用於配置所有的第三方模塊加載器 rules: [ {test: /\.css$/, use:['style-loader','css-loader']},//配置處理.css文件的第三方處理規則 {test: /\.less$/, 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.還需要載webpack.config.js配置文件中加兩行代碼:
const VueLoaderPlugin = require('vue-loader/lib/plugin');
new VueLoaderPlugin()
三、補充出錯原因
- vue-loader@15.*之后 必須配置帶有VueLoaderPlugin 之外,還需另外單獨配置css-loader。
- 如果是用最新webpack原生構建,除了安裝webpack外,還要安裝webpck-cli,在webpack.config中配置mode選項
- 為保持構建環境一致,請采用`npm run dev`腳本編譯的形式,以確保使用的webpack命令,vue-loader是本地版本。
