我的文件结构：

-.meteor
-client
-server
-public
-lib (collections.js here)

collections.js：

Games = new Mongo.Collection('games');

在升级到1.3之前，一切正常。

Answer 1

在Meteor 1.3推荐的方式中，使用import而不是将所有内容都移动到全局。

// collections.js
export const Games = new Mongo.Collection('games');

然后

// any_other_file.js
import { Games } from '../lib/collections'

Answer 2

而不是

Games = new Mongo.Collection('games');

DO

global.Games = new Mongo.Collection('games');

becouse

在测试版5中，全局变量存在问题。
