vue使用oss報錯

ali-oss庫
單獨在app.js文件里寫，查文件和上傳文件都正常

var co = require('co');
var OSS = require('ali-oss');

var client = new OSS({
  region: 'oss-cn-hangzhou',
  accessKeyId: 'LzAIxNFeBahZIdN',
  accessKeySecret: 'hvRjK9bNdr1gSnrcd31T6IJZGHBG2T'
});

co(function* () {
  var result = yield client.listBuckets();
  console.log(result);
}).catch(function (err) {
  console.log(err);
});

...

但是放在VUE中，則提示沒有l(wèi)istBuckets函數(shù)
