想把自定義一些js function單獨(dú)寫到一個文件config.js
然后在main.js import:

import config from './config.js'

結(jié)果報錯：

[HMR] bundle has 1 errors   client.js?7955:161 ./src/main.js
[HMR] bundle has 1 errors   client.js?7955:161 ./src/main.js

  ?  http://eslint.org/docs/rules/no-unused-vars  'config' is defined but never used  
  src\main.js:11:8
  import config from './config.js'
          ^


? 1 problem (1 error, 0 warnings)


Errors:
  1  http://eslint.org/docs/rules/no-unused-vars
 @ multi ./build/dev-client ./src/main.js

無奈在main.js 加入：

console.info(config)

就不報錯了。

這個是哪個環(huán)節(jié)搞的呢？？
