“以代码8退出"；样本流星应用 [英] "Exited with code 8" Sample meteor applications

问题描述

我是Meteor.js的新手，目前正在使用"leaderboard"示例应用程序.插入一行代码后:

I am new to Meteor.js and currently working on the "leaderboard" example app. After inserting a line of code:

Template.leaderboard.player = function(){
  return "Some other text"
}

我在应用程序界面中收到错误:

I received the error in the app's interface:

您的应用程序崩溃了.这是最新的日志."

"Your app is crashing. Here is the latest log."

你好世界

我重新保存文件，进入终端并停止服务器，然后重新启动并收到以下消息:

I re-saved the file, went into the terminal and stopped the server and restarted it and received this:

我的研究表明'Exited with code: 8'是一个错误，通常与尝试更改db有关.我对流星很陌生，感谢您的投入.

My research has indicated that 'Exited with code: 8' is an error often associated with try to change db's. I am very new to meteor and input is appreciated.

推荐答案

确保在if(Meteor.isClient){}块内添加了Template帮助器代码.如果在公共区域添加了代码，它将尝试在服务器端也运行代码，显然Template在服务器端不可用.

Make sure that you added the Template helper code inside if(Meteor.isClient){} block. If you added the coded in a common area it will try to run the code in the server side also and obviously Template is not available in server side.

if (Meteor.isClient) {
  Template.leaderboard.helpers({
    players: function () {
      return "Some other text"
  }
});
