【问题描述】：

我正在从书 Your First Application 中学习流星，我被困在 4.2 创建一个集合。当我刷新我的网页时，会出现：

Your app is crashing. Here's the latest log.

【问题讨论】：

能把服务器文件放上来吗？
你已经定义了两次Mongo.Collection("players")
console.log("Hello world!");新的 Mongo.Collection('players'); PlayersList = new Mongo.Collection('players'); if (Meteor.isClient) { } if (Meteor.isServer) { }
摆脱多余的new Mongo.Collection('players'); 我认为您应该在执行此操作之前尝试一堂codeacademy javascript课程，您对基本编程以及代码的作用缺乏重要的了解。
非常感谢你们

我也遇到了同样的问题，看来你需要将 Template.form 定义 inside 包装为 Meteor.isClient 条件，像这样：

if(Meteor.isClient){
    Template.leaderboard.helpers({
    "player": function(){
    return "doesn't work!"
   }
 });
}
