截至2018-06-05 最新稳定版本为 8.11.2,直接 next ,不改目录。
PS C:\Users\Administrator> node -v
v8.11.2
PS C:\Users\Administrator> npm -v
5.6.0
npm config set registry https://registry.npm.taobao.org
npm info underscore (如果上面配置正确这个命令会有字符串response)
或者直接编辑 ~/.npmrc(比如 C:\Users\Administrator\.npmrc )加入下面内容。
registry = https://registry.npm.taobao.org
截至2018-06-05 最新版本为 2.9.6。带上版本号,大家用同一个版本。
npm i vue-cli@2.9.6 -g
安装完成后,校验是否安装成功
PS C:\Users\Administrator> vue -V
2.9.6
使用 vue init 命令初始化项目
vue init webpack
? Generate project in current directory? (Y/n)
// 是否在当前文件夹下创建项目: 输入y, 回车
? Project name (vue-learn-demo)
// 项目名称:不输入,直接回车
? Project description (A Vue.js project)
// 项目描述:不输入,直接回车
? Author (fefuns <1321120469@qq.com>)
// 作者: 不输入,直接回车
? Vue build (Use arrow keys)
> Runtime + Compiler: recommended for most users
Runtime-only: about 6KB lighter min+gzip, but templates (or any Vue-specific HTML) are ONLY allowed in .vue files - render functions are required elsewhere
// 第一个是vue官方推荐大部分用户用这个,这个表示可以不基于 .vue 文件做开发,可以在运行时做编译,因为它有一个 compiler。
// 如果选第二个,min + gzip后,vuejs文件会减小6KB,因为它省略了templates模板的编译过程, 因为这个编译过程是webpack 用 vue-loader 去编译.vue 做的, 但是必须依赖 .vue文件做开发。
// 上下箭头选第二个,回车。
? Install vue-router? (Y/n)
// 是否安装路由:输入 y, 回车
? Use ESLint to lint your code? (Y/n)
// 是否使用 ESlint 规范代码:输入 y, 回车
? Pick an ESLint preset (Use arrow keys)
> Standard (https://github.com/standard/standard)
Airbnb (https://github.com/airbnb/javascript)
none (configure it yourself)
// 选择哪种 ESlint 规范预设。选择 standard 规范
? Set up unit tests (Y/n)
// 是否设置单元测试:输入 n, 回车
? Setup e2e tests with Nightwatch? (Y/n)
// 是否用 Nightwatch 设置 E2E 测试:输入 n,回车
? Should we run `npm install` for you after the project has been created? (recommended) (Use arrow keys)
> Yes, use NPM
Yes, use Yarn
No, I will handle that myself
// 是否在创建完项目后自动安装依赖,并选择一种依赖管理工具。
// 选择 npm, 回车
进行完以上步骤,执行 npm run dev 即可打开 http://localhost:8080 开发环境
vue-cli@2.9.6 生成的项目,默认加入了处理sass的loader, 但是并没有将依赖写在package.json中。
所以想在 .vue文件里使用scss
<style scoped lang="scss">
<style>
得自己安装依赖:其中安装sass-loader前需要提前安装node-sass。如果你以后做的项目样式是用less的话,安装less-loader前需要安装less。以下为安装node-sass 与 sass-loader
npm install sass-loader node-sass --save-dev
npm install --save-dev node-sass --registry=https://registry.npm.taobao.org --disturl=https://npm.taobao.org/dist --sass-binary-site=http://npm.taobao.org/mirrors/node-sass
可以理解为jquery项目中的ajax
npm i axios -S
// 相当于 npm install axios --save
在项目中全局引入,修改 src/main.js
import axios from ‘axios‘
...
Vue.prototype.$http = axios
npm i vuex -S
// 相当于 npm install vuex --save
在项目中全局引入,修改 src/main.js
import Vuex from ‘vuex‘
...
vue.use(Vuex)
npm i element-ui -S
在项目中全局引入,修改 src/main.js
import ElementUI from ‘element-ui‘
import ‘element-ui/lib/theme-chalk/index.css‘
...
Vue.use(ElementUI)
Babel 默认只转换新的 JavaScript 语法,而不转换新的 API。例如,Iterator、Generator、Set、Maps、Proxy、Reflect、Symbol、Promise 等全局对象,以及一些定义在全局对象上的方法(比如 Object.assign)都不会转译。如果想使用这些新的对象和方法,必须使用 babel-polyfill,为当前环境提供一个垫片。
babel-runtime 是为了减少重复代码而生的。babel-runtime插件能够将这些工具函数的代码转换成require语句,指向为对babel-runtime的引用。
以插件的形式在打包时引入到文件里
vue-cli生成的项目自带了有babel-plugin-transform-runtime
npm i babel-runtime -S
// 相当于 npm install babel-runtime --save
npm i babel-polyfill -D
// 相当于 npm install babel-polyfill --save-dev
在项目中全局引入,修改 src/main.js, 在第一行加入
import ‘babel-polyfill‘
注意 bable-polyfill 必须写在最上面,而babel-runtime是不需要引入的
--save-dev 是你开发时候依赖的东西,--save 是你发布到线上之后还依赖的东西。
比如,你写 ES6 代码,如果你想编译成 ES5 发布那么 babel 就是devDependencies。 如果你用了 axios,由于发布之后还是依赖 axios 处理数据请求,所以是dependencies。
import ‘babel-polyfill‘
import Vue from ‘vue‘
import router from ‘./router‘
import Vuex from ‘vuex‘
import axios from ‘axios‘
import ElementUI from ‘element-ui‘
import ‘element-ui/lib/theme-chalk/index.css‘
import App from ‘./App‘
Vue.config.productionTip = false
Vue.use(Vuex)
Vue.use(ElementUI)
Vue.prototype.$http = axios
/* eslint-disable no-new */
new Vue({
el: ‘#app‘,
router,
render: h => h(App)
})

涉及到工程化的项目,不再建议使用轻量级编辑器sublime,推荐使用vscode或webstorm。
以vscode为例,为了更高效的编写vue项目,至少需要做以下配置:
主要是用于让vscode能识别vue文件,对vue代码进行高亮处理
