javascript - "Exited with code 8" meteor 应用示例

Question

我是 Meteor.js 的新手，目前正在开发 “leaderboard” 示例应用程序。插入一行代码后:

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

我在应用程序的界面中收到错误消息:

“您的应用程序崩溃了。这是最新的日志。”

我重新保存文件，进入终端并停止服务器并重新启动它并收到这个:

我的研究表明 'Exited with code: 8' 是一个错误，通常与尝试更改数据库有关。我是 meteor 的新手，非常感谢您的意见。

确保您在 if(Meteor.isClient){} block 中添加了 Template 帮助程序代码。如果您在公共(public)区域添加代码，它也会尝试在服务器端运行代码，显然 Template 在服务器端不可用。

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