我有非常奇怪的问题，完全不知道如何解决它。
我正在尝试构建非常简单的fullpage.js和meteor.js实现。下面的代码有效，但几分钟后，它就会中断。当我打开一个新的隐身窗口时，它再次工作几分钟，但是当我刷新页面时，我得到以下错误3次（每个文档收集一次）。
Exception in queued task: Error: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.

在<div>周围添加{{#each products}}可能会解决您的问题。
我不熟悉fullpage.js，但我收到了与maazalik：malihu-jquery-custom-scrollbar包完全相同的错误消息。该插件通过将元素复制并粘贴到新div中来操作，如果该元素的第一个子元素是{{#each}}或{{#if}}，则可能会导致问题。添加<div>解决了这个问题。
您可以在此github issue找到更多信息。

您可以尝试在每个函数中添加else以查看它是否解决了什么问题？
<template name="fullPage">
<div id="fullpage" class="section">
{{#each products}}
<div class="slide"><h2>{{name}}</h2></div>
{{else}}
{{! does this help? }}
{{/each}}
</div>
</template>
