当startup.js加载以使用Mongo时流星崩溃

Question

I am creating a Mongo database for meteor. 我正在为流星创建一个Mongo数据库。 I create a startup.js file, so meteor can load the files. 我创建了一个startup.js文件，以便流星可以加载这些文件。 as soon as meteor starts it crashes. 流星一开始它就崩溃了。 can anyone help me pls? 有人可以帮我吗？

html file html文件

<body>
  <div class="container">
    {{> images}}
  </div>
</body>
<template name="images">
  <div class="row">
    {{#each images}}
    <div class="col-xs-12 col-md-3">
      <div class="thumbnail">
        <img class="js-image" src="{{img_src}}" alt="{{img_alt}}" />
      </div>
    </div>
    {{/each}}
  </div>
</template>

startup.js file startup.js文件

if (Meteor.if(Meteor.isServer) {
    Meteor.startup(function() {
        if (Images.find().count() == 0) {
          Images.insert({
              img_src: "laptops.jpg",
              img_alt: "some laptops on a table"
            }
          })
      }
    });
})

image_share.js image_share.js

Images = new Mongo.Collection("images");
if (Meteor.isClient) {
  var img_data = [{
    img_src: "laptops.jpg",
    img_alt: "some laptops on a table"
  }, {
    img_src: "bass.jpg",
    img_alt: "a bass player"
  }, ];
  Template.images.helpers({
    images: img_data
  });
  Template.images.events({
    'click .js-image': function(event) {
      $(event.target).css("width", "50px");
    }
  });
}

if (Meteor.if(Meteor.isServer)) {
    Meteor.startup(function() {
        if (Images.find().count() == 0) {
            Images.insert({
                img_src: "laptops.jpg",
                img_alt: "some laptops on a table"
            });
        }
    });
}

You forgot one closing ")" and some others was wrong. 您忘记了一个结尾的“）”，而另一些则是错误的。
