根目录下新建webstorm.config.js，写入

'use strict'
const path = require('path')

function resolve (dir) {
  return path.join(__dirname, '.', dir)
}

module.exports = {
  context: path.resolve(__dirname, './'),
  resolve: {
    extensions: ['.js', '.vue', '.json'],
    alias: {
      '@': resolve('src'),
      '_c': resolve('src/components')
    }
  }
}

然后导入到webstorm下即可，如下图
