将 Meteor 版本从 1.2 升级到 1.3 后，我收到此错误：

我的文件结构：

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

收藏.js：

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

在升级到1.3之前，一切正常。

Answer 1

在 Meteor 1.3 中，推荐的方法是使用 import 而不是将所有内容移动到全局中。

// 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');

做

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

贝库斯

在beta 5中，全局变量遇到了问题。
