为了兼容ie11在webpack+babel打包vue.js后发现报错"ReferenceError: “i”未定义"

问题:使用webpack+babel打包es6=>es5,运行打包后的项目报错"ReferenceError: “i”未定义",页面空白,babel-polyfill已经引入。

!!!!但是,在Chrome中可以正常运行不报错说明应该不是代码问题,那就应该还是打包的问题吧,请大佬指点指点!!!!!!!

vue打包后iphone 5c ios10.3.3打开报错,调试时无错误. 求解决办法

### 问题描述: 公司测试小哥的苹果5c在本地调试的时候是可以打开的. 蓝后.. 打包后页面打开空白,在别的手机上表现良好.(可能安卓低版本也会报错吧) ### 环境背景及尝试过的方法: 出现问题的手机是 10.3ios版本的苹果5c 问题出现后, 我尝试加载 babel-polyfill,es6-promise但没有卵用,依旧报同样的错误 ### 相关代码 ``` main.js中 import 'babel-polyfill' import Es6Promise from 'es6-promise' require('es6-promise').polyfill() Es6Promise.polyfill() webpack.base.conf.js中也尝试过 entry: { app: ["babel-polyfill","./src/main.js"] } ``` ### 报错 1. SyntaxError: Cannot declare a let variable twice: 't'. vendor.js 2. TypeError: undefined is not an object (evaluating 'r[n].call') 各位大佬请问是我的开发方式不对吗? 寻求解决办法 .babelrc 代码 ``` { "presets": [ ["env", { "modules": false, "targets": { "browsers": ["> 1%", "last 2 versions", "not ie <= 8"] } }], "stage-2" ], "plugins": ["transform-vue-jsx", "transform-runtime"], "env": { "test": { "presets": ["env", "stage-2"], "plugins": ["istanbul"] } } } ``` webpack.base.conf.js ``` 'use strict' const path = require('path') const utils = require('./utils') const config = require('../config') const vueLoaderConfig = require('./vue-loader.conf') function resolve (dir) { return path.join(__dirname, '..', dir) } module.exports = { context: path.resolve(__dirname, '../'), entry: { app: ["./src/main.js"] }, output: { path: config.build.assetsRoot, filename: '[name].js', publicPath: process.env.NODE_ENV === 'production' ? config.build.assetsPublicPath : config.dev.assetsPublicPath }, plugins: [ new webpack.ProvidePlugin({ $: "jquery", jQuery: "jquery", "windows.jQuery": "jquery" }) ], resolve: { extensions: ['.js', '.vue', '.json'], alias: { 'vue$': 'vue/dist/vue.esm.js', '@': resolve('src'), } }, module: { rules: [ { test: /\.vue$/, loader: 'vue-loader', options: vueLoaderConfig }, { test: /\.js$/, loader: 'babel-loader', include: [resolve('src'), resolve('test'), resolve('node_modules/webpack-dev-server/client')] }, { test: /\.(png|jpe?g|gif|svg)(\?.*)?$/, loader: 'url-loader', options: { limit: 10000, name: utils.assetsPath('img/[name].[hash:7].[ext]') } }, { test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/, loader: 'url-loader', options: { limit: 10000, name: utils.assetsPath('media/[name].[hash:7].[ext]') } }, { test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/, loader: 'url-loader', options: { limit: 10000, name: utils.assetsPath('fonts/[name].[hash:7].[ext]') } } ] }, node: { // prevent webpack from injecting useless setImmediate polyfill because Vue // source contains it (although only uses it if it's native). setImmediate: false, // prevent webpack from injecting mocks to Node native modules // that does not make sense for the client dgram: 'empty', fs: 'empty', net: 'empty', tls: 'empty', child_process: 'empty' } } ```

自己用webpack构建vue项目报错,求帮助万分感谢

神烦怎么也解决不了问题,用localhost能访问到的是目录 用node:{ fs: 'empty', net: 'empty', tls: 'empty', child_process: 'empty' }能减少几个报错信息 以下是我的配置 ``` const path = require('path'); const HTMLPlugin = require('html-webpack-plugin'); const VueLoaderPlugin = require('vue-loader/lib/plugin'); const webpack = require('webpack'); const isDev = process.env.NODE_ENV === 'development'; //package.json设置的对象全部存在process.env里面 const config = { target: 'web', entry: path.join(__dirname, 'src/index.js'),//设置入口,__dirname代表本文件所在的地址,也就是根目录 output: { filename: 'bundle.js', //打包的名字 path: path.join(__dirname, 'dist') //打包路径 }, plugins: [ // make sure to include the plugin for the magic new VueLoaderPlugin(), new webpack.DefinePlugin({ 'process.env': { NODE_ENV: isDev ? '"development"' : '"production"' //调用process.env.NODE_ENV 可以获取 环境 } }), new HTMLPlugin() ], module: { rules: [ { test: /\.vue$/, loader: 'vue-loader' }, { test: /\.css$/, use: [ 'style-loader',

js 错误对象 err.stack 用“console 控制台输出”与“实际字符串”不一致问题

背景:最近在做一个前端错误监控系统,要求收集 js 错误信息堆栈等。使用 vue+webpack 技术。 js 错误对象 Error 下的错误堆栈 stack 。 ``` const error = new TypeErrpr(); console.log(error.stack); // console 控制台输出 JSON.stringify(error.stack); // 实际字符串 ``` 使用 console.log 控制台输出如下(显示行号、堆栈信息正确): ``` TypeError: this.b is not a function at Object.aa (common.js?cf45:119) at VueComponent.errorInJSHandler (Home.vue?76f2:104) at invokeWithErrorHandling (vue.runtime.esm.js?2b0e:1854) at VueComponent.invoker (vue.runtime.esm.js?2b0e:2179) at invokeWithErrorHandling (vue.runtime.esm.js?2b0e:1854) at VueComponent.Vue.$emit (vue.runtime.esm.js?2b0e:3888) at VueComponent.handleClick (element-ui.common.js?5c96:9417) at invokeWithErrorHandling (vue.runtime.esm.js?2b0e:1854) at HTMLButtonElement.invoker (vue.runtime.esm.js?2b0e:2179) at HTMLButtonElement.original._wrapper (vue.runtime.esm.js?2b0e:6917) ``` 但如果直接在页面显示或者保存为字符串,变成如下(显示行号、堆栈信息错误): ``` TypeError: this.b is not a function at Object.aa (webpack-internal:///./src/utils/common.js:173:10) at VueComponent.errorInJSHandler (webpack-internal:///./node_modules/cache-loader/dist/cjs.js?!./node_modules/babel-loader/lib/index.js!./node_modules/cache-loader/dist/cjs.js?!./node_modules/vue-loader/lib/index.js?!./src/views/Home.vue?vue&type=script&lang=js&:108:61) at invokeWithErrorHandling (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:1853:26) at VueComponent.invoker (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:2178:14) at invokeWithErrorHandling (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:1853:26) at VueComponent.Vue.$emit (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:3882:9) at VueComponent.handleClick (webpack-internal:///./node_modules/element-ui/lib/element-ui.common.js:9417:12) at invokeWithErrorHandling (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:1853:26) at HTMLButtonElement.invoker (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:2178:14) at HTMLButtonElement.original._wrapper (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:6907:25) ``` 怀疑是经过 webpack 打包的坑,想问各位,我如何才能获取到正确的堆栈信息( console.log 控制台输出)? ## **补充:**已找到解决方法,使用mozilla的sourcemap库(https://github.com/mozilla/source-map#sourcemapconsumerwith)即可通过打包后的错误堆栈及sourceMap文件中找到正确行列位置、文件名字等信息

Vue-cli 的热更新无效问题

我使用vue init webpack-simple ProjectName创建了一个简单的Vue-cli工程,但是无法实现热更新。每次一点点改动就需要重新编译运行才能看到效果,十分困扰。 我的webpack配置如下: ``` const path = require('path') const webpack = require('webpack'); console.log(path.resolve(__dirname, './src/main.js')) module.exports = { //热部署 entry:[ path.resolve(__dirname, './src/main.js'), 'webpack-dev-server/client?http://localhost:8080/', ], output: { path: path.resolve(__dirname, './dist'), publicPath: './dist/', filename: 'build.js' }, module: { rules: [ { test: /\.css$/, use: [ 'vue-style-loader', 'css-loader' ], }, { test: /\.vue$/, loader: 'vue-loader', options: { loaders: { } // other vue-loader options go here } }, { test: /\.js$/, loader: 'babel-loader', exclude: /node_modules/ }, { test: /\.(png|jpg|gif|svg)$/, loader: 'file-loader', options: { name: '[name].[ext]?[hash]' } } ] }, resolve: { alias: { 'vue$': 'vue/dist/vue.esm.js' }, extensions: ['*', '.js', '.vue', '.json'] }, devServer: { //这里可以配置端口号 // port:8080, // host: 'localhost', //重定向404 historyApiFallback: true, noInfo: true, //编译出错的时候,在浏览器页面上显示错误 overlay: true, hot:true, inline:true, //该目录不填默认是项目目录 // contentBase: path.resolve(__dirname), }, performance: { hints: false }, devtool: '#eval-source-map', //配置webpack插件 plugins:[ //热加载插件 new webpack.HotModuleReplacementPlugin(), new webpack.NamedModulesPlugin(), ] } if (process.env.NODE_ENV === 'production') { module.exports.devtool = '#source-map' // http://vue-loader.vuejs.org/en/workflow/production.html module.exports.plugins = (module.exports.plugins || []).concat([ new webpack.DefinePlugin({ 'process.env': { NODE_ENV: '"production"' } }), new webpack.optimize.UglifyJsPlugin({ sourceMap: true, compress: { warnings: false } }), new webpack.LoaderOptionsPlugin({ minimize: true }) ]) } ``` package.json如下: ``` { "name": "srms", "description": "A Vue.js project", "version": "1.0.0", "author": "Snile <826245622@qq.com>", "license": "", "private": true, "scripts": { "clean": "rd /s /q dist", "build": "cross-env NODE_ENV=production webpack --progress --hide-modules", "dev": "npm run build && cross-env NODE_ENV=development webpack-dev-server --open --inline --hot" }, "dependencies": { "vue": "^2.5.11", "vue-router": "^3.0.2" }, "browserslist": [ "> 1%", "last 2 versions", "not ie <= 8" ], "devDependencies": { "babel-core": "^6.26.0", "babel-loader": "^7.1.2", "babel-preset-env": "^1.6.0", "babel-preset-stage-3": "^6.24.1", "cross-env": "^5.0.5", "css-loader": "^0.28.7", "file-loader": "^1.1.4", "vue-loader": "^14.2.3", "vue-template-compiler": "^2.4.4", "webpack": "^3.12.0", "webpack-dev-server": "^2.9.1" } } ``` 该配置似乎能检测到文件的变化,每次改动后,控制台都会输出: client:77 [WDS] Hot Module Replacement enabled. 2client:80 [WDS] App updated.
