项目框架搭建
1.使用vue create快速搭建vue项目
2.使用VC Code打开新生成的项目
- 端口号简单配置
修改
vue.config.js文件，内容修改如下
所需库安装
npm install vue-resource --save --no-fund
npm install vue-router@3 --save --no-fund
npm install axios --save --no-fund
关闭eslint检测
修改.eslintrc.js文件，注释掉
'eslint:recommended'，并在rules中加上"vue/no-unused-components":"off"不关闭检测，组件注册后未被使用时，会直接报错导致项目无法运行
