在将Meteor版本从1.2升级到1.3之后，我得到了以下错误：

我的档案结构：

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

collections.js：

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

在升级到1.3之前，一切都很好。

Answer 1

而不是

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

做

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

因为

在beta 5中，全球都有问题。

Answer 2

在Meteor1.3中，推荐的方法是使用import，而不是将所有东西都迁移到全局。

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

然后

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