javascript - 如何使用yield和Iron-router？

Question

所以我现在正在尝试做一个基本的 meteor 应用程序..这是三个文件。

路由器.js:

Router.configure({
    layoutTemplate : 'layout',
    loadingTemplate : 'loading',
    notFoundTemplate : 'notFound'
});

Router.route("/", {
    name : "homeIndex",
    data : function() {
        return {
            message : "Welcome to the Rocket Shop"
        }
    }
});

index.html:

<template name="homeIndex">
    <h1>{{message}}</h1>
</template>

布局.html:

<template name="layout">
        {{> nav}}
        <div class="container">
            {{>yield}}
        </div><!-- /.container -->
</template>

当我启动应用程序后转到 localhost:3000 时，我的浏览器控制台中会出现很长的堆栈跟踪，并且页面正文不会加载。

有人知道我做错了什么吗？我只是遵循pluralsight 教程并遵循了所有指示。

Answer 1

在 stackoverflow 搜索其他 Iron-router 问题后，我找到了自己问题的答案。我不知道它为什么有效，但它解决了问题。我所要做的就是运行:

meteor add ejson

我不再犯错误了。
