我是ember.js的新手。我设法使用Grunt文件预编译模板。但是，当我将它们包含在index.html中时，我看到一个空页面，不会呈现模板。我究竟做错了什么？如果我不编译模板并直接包含在index.html中，那就可以了。
我使用yeoman.io安装了所有东西（使用bower包grunt-ember-templates，ember，webapp scaffolding）
我的index.html：
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>My New App</title>
<meta name="description" content="">
<meta name="viewport" content="width=device-width">
<link rel="shortcut icon" href="/favicon.ico">
<link rel="stylesheet" href="css/style.css">
</head>
<body>
<script src="bower_components/jquery/dist/jquery.js"></script>
<script src="bower_components/handlebars/handlebars.js"></script>
<script src="bower_components/ember/ember.js"></script>
<script src="scripts/templates.js"></script>
<script src="scripts/app.js"></script>
</body>
</html>
我的App.js：
App = Ember.Application.create();
App.Router.map(function() {
// put your routes here
});
App.IndexRoute = Ember.Route.extend({
model: function() {
return ['red', 'yellow', 'blue'];
}
});
模板：
编辑：application.hbs
<h2>Welcome to Ember.js</h2>
{{outlet}}
编辑：index.hbs
<ul>
{{#each item in model}}
<li>{{item}}</li>
{{/each}}
</ul>
templates.js中的已编译模板：
define(["ember"], function(Ember){
Ember.TEMPLATES["application"] = Ember.Handlebars.template(function anonymous(Handlebars,depth0,helpers,partials,data) {
this.compilerInfo = [4,'>= 1.0.0'];
helpers = this.merge(helpers, Ember.Handlebars.helpers); data = data || {};
var buffer = '', stack1;
data.buffer.push("<h2>Welcome to Ember.js</h2>\n\n");
stack1 = helpers._triageMustache.call(depth0, "outlet", {hash:{},hashTypes:{},hashContexts:{},contexts:[depth0],types:["ID"],data:data});
if(stack1 || stack1 === 0) { data.buffer.push(stack1); }
return buffer;
});
Ember.TEMPLATES["index"] = Ember.Handlebars.template(function anonymous(Handlebars,depth0,helpers,partials,data) {
this.compilerInfo = [4,'>= 1.0.0'];
helpers = this.merge(helpers, Ember.Handlebars.helpers); data = data || {};
var buffer = '', stack1, self=this;
function program1(depth0,data) {
var buffer = '', stack1;
data.buffer.push("\n <li>");
stack1 = helpers._triageMustache.call(depth0, "item", {hash:{},hashTypes:{},hashContexts:{},contexts:[depth0],types:["ID"],data:data});
if(stack1 || stack1 === 0) { data.buffer.push(stack1); }
data.buffer.push("</li>\n ");
return buffer;
}
data.buffer.push("\n<ul>\n ");
stack1 = helpers.each.call(depth0, "item", "in", "model", {hash:{},hashTypes:{},hashContexts:{},inverse:self.noop,fn:self.program(1, program1, data),contexts:[depth0,depth0,depth0],types:["ID","ID","ID"],data:data});
if(stack1 || stack1 === 0) { data.buffer.push(stack1); }
data.buffer.push("\n</ul>\n");
return buffer;
});
});

您没有具体说明如何编译模板。它们来自* .hbs文件，还是您使用的是其他方法？
在我看来，您正在尝试将templates.html文件编译为单个模板，因为它在模板本身中包含此代码：
data.buffer.push("\n<script type=\"text/x-handlebars\">\n
每个模板文件应仅包含模板的内容，而不包含脚本标记本身。
通常，您将每个.hbs文件放在一个单独的文件中，该文件与用于确定模板名称的文件一起使用。
我之前做了一个演示，我正在使用grunt对应用程序进行实时编码。此截屏视频确实显示了如何组织.hbs文件，而源代码显示了如何编译它们。这显示了我的开发过程，并通过使用grunt构建一个完整的应用程序作为构建系统。

希望有所帮助！

我通过从grunt-ember-templates grunt配置中删除amd：true选项解决了这个问题。说实话，我已经添加它而不知道它做了什么。
为了完整性，这是我当前的grunt文件。这个文件是由yeoman.io webapp生成器自动生成的，我只添加了一个grunt-ember-templates配置（在emberTemplates下定义）。
截至今天，我在网上发现的所有指南都不完整或已过时，这对我有用。
