把手没有出口？

Question

问题

执行已编译的车把模板时，不会导出全局Handlebars对象。 注意：全局Backbone对象正在运行。

请参阅代码App.templates.todos尝试在todos.js文件中执行时失败，因为未定义App.templates.todos。最终这是因为templates.js文件中的第三行无法执行，因为未定义全局Handlebars对象。

为什么不定义该对象？我在require.js做错了什么？

更新：我已经确认handlebars.runtime.js文件实际上正在执行 templates.js文件，因此require.js在加载todos.js文件时以正确的顺序运行它们。

来自RequireJS的official documentation：

  

shim配置只设置代码关系。加载模块   属于或使用shim配置，正常的require / define调用是   需要。设置填充程序本身不会触发加载代码。

首先，您需要以某种方式调用Handlebars并尝试在templates.js中使用它。
