配置 uni-app eslint_uni is not defined

编辑器：vs code
脚手架：uni-app
eslint标准：Standard

1. 下载安装uni-app项目
2. vs code安装插件ESLint
3. 下载安装eslint-config-standard github地址：eslint语法检查standard
   在当前项目中执行npx eslint --init（npx是npm包中带有的一个命令），如上图选择安装成功完毕后，项目工程目录下会自动生成.eslintrc.js文件。此时你的语法检查已经生效（未生效请重启vs code）。
4. 其他配置
   uni-app中带有全局变量uni，eslint会报错uni is not undefined, 我们需要在.eslintrc.js文件gloabls选项中中配置uni: true。或者对单文件配置注释/global xxxx/（治标不治本）

5.其他的如代码自动矫正功能，请结合网上的说明自行配置setting。
