eslint在webstorm中有错误警告

1. 报错missing space before function parentheses的问题

　　解决：在代码目录中，打开.eslint文件，并在rules中添加如下一行代码即可：

　　

 

　　"space-before-function-paren": 0

2. 报错eslint: missing semicolon

　　解决：在rules中添加

　　"semi": [2, "always"] // 设置强制加分号

 

 

3.报错eslint: string must be use singlequote
　　解决：在rules中添加

  "quotes": [1, "single"], //引号类型 `` "" ''
