vue eslint报错Unexpected token import解决

vue项目执行 npm run serve 启动时报以下错误（实际错误很多，仅复制两个）

 error  in ./src/router/index.js

Module Error (from ./node_modules/eslint-loader/index.js):
error: Parsing error: Unexpected token import at src\router\index.js:11:26:

     |                          ^
  12 |         redirect: '/subscribe',

Module Error (from ./node_modules/eslint-loader/index.js):

  4 |             this.setLogoAndTitle(this.$localstore.get('logoTitle'));
  5 |             await this.setLogoTitle();
  6 |         },

原因是eslint校验代码时babel还未处理代码，
在.eslintrc.js中 extends: [], 删掉所有，只保留'plugin:vue/essential' 一项
