工欲善其事必先利其器,首先我们得有一个趁手的ide,一直习惯使用phpstorm,但是Ctrl+Alt+l的格式化实在满足不了ESLint校验我们写的代码!
1.phpstorm配置ESlint检查代码

Ctrl+ALT+L是phpstorm自带的快速格式化的缩进量，我们需要配置eslint格式化快捷键。如图添加快捷键ALT+L即可，以后就可以用Alt+L格式化成符合eslint规则的格式代码。

此时使用Alt+L就可以爽歪歪的使用代码格式化了
2.phpstorm在vue文件中使用stylus

以下插件也可以一并安装

装完后记得重启!
3.安装vue-cli
安装前记得切换国内源
npm config set registry https://registry.npm.taobao.org
npm i -g cnpm
npm info underscore
// 有 registry.npm.taobao.org 等字样 说明切换成功
接着安装vue-cli
npm i -g @vue/cli@3
4.初始化vue项目
vue init webpack admin
[图片上传中...(image.png-a9f0fd-1561989872025-0)]
按照图片指示操作即可
安装element-ui
npm i element-ui –S
安装axios
npm i axios -S
安装 avue
npm i @smallwei/avue -S
使用方式:
import Avue from '@smallwei/avue';
import '@smallwei/avue/lib/index.css';
Vue.use(Avue);
安装js-cookie插件
npm install js-cookie --save
安装vuex
npm install vuex --save
如果出现 Module not found: Error: Can't resolve 'sass-loader'
安装下下面扩展即可
npm install node-sass --save-dev
npm install sass-loader --save-dev
安装vue版本ECharts
npm install vue-echarts --save
