Question

我正在关注流星站点教程（https://www.meteor.com/tutorials/blaze/collections）。

但是当你添加这一行时：

export const Tasks = new Mongo.Collection（＆＃39; tasks＆＃39;）;

我收到以下错误：

						throw(ex);

教程中的一行：

export const Tasks = new Mongo.Collection('tasks');

与您的行不同：

Export Tasks const = new Mongo.Collection ('tasks');

代码的目标是初始化一个新常量Tasks，将其设置为新的Mongo.Collection，然后将其导出。
