vue-loader加载不上怎么解决?很多新手对此不是很清楚,为了帮助大家解决这个难题,下面小编将为大家详细讲解,有这方面需求的人可以来学习下,希望你能有所收获。
vue-loader 是要依赖 vue 的,所以先下载 vue
npm i vue -S
cnpm i vue-loader vue-template-compiler -D
webpack.config.js 中配置相关信息 注意:这里配置好了
再给大家看一下 我的 package.json 文件
注意:
css-loader style-loader 等等 我都已经下载配置完成
{ "name": "webpack-study", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "dev": "webpack-dev-server --open --port 3000 --contentBase src --hot" }, "keywords": [], "author": "", "license": "ISC", "devDependencies": { "babel-core": "^6.26.3", "babel-loader": "^7.1.5", "babel-plugin-transform-runtime": "^6.23.0", "babel-preset-env": "^1.7.0", "babel-preset-stage-0": "^6.24.1", "css-loader": "^1.0.0", "file-loader": "^2.0.0", "html-webpack-plugin": "^3.2.0", "less": "^3.8.1", "less-loader": "^4.1.0", "node-sass": "^4.9.3", "sass-loader": "^7.1.0", "style-loader": "^0.22.1", "url-loader": "^1.1.1", "vue-loader": "^15.4.1", "vue-template-compiler": "^2.5.17", "webpack": "^4.17.1", "webpack-dev-server": "^3.1.5" }, "dependencies": { "vue": "^2.5.17", "webpack-cli": "^3.1.0" } }
重头戏来了,即使这样 运行 : npm run dev
仍然无法识别 vue-loader
错误原因:
vue-loader@15.*之后除了必须带有VueLoaderPlugin
解决方案:
需要使用插件VueLoaderPlugin
在webpack.config.js里用const VueLoaderPlugin = require('vue-loader/lib/plugin')引入,
然后在module.exports对象里添加plugins:[new VueLoaderPlugin()]
再次 运行 项目 就可以啦~~~
补充知识:vue-loader加载不上报错* ./node_modules/vue-loader/lib/index.js You may need an additional loader to handle
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. | > <h2>这是使用.vue文件渲染出来的</h2> | | @ ./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
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$/, use: 'vue-loader'} ] } };
出来需要配置{test: /\.vue$/, use: 'vue-loader'}这个外,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()
