Ember-CLI - 运行默认应用程序时出错

Question

尝试运行一个简单的、空的基于 Ember-CLI 的应用程序，但它在控制台中生成错误：

找不到“索引”模板或视图。什么都不会被渲染 对象

试图围绕 Ember 和 Ember-CLI 展开思考，但我什至不知道从哪里开始！

来自控制台的完整日志是：

这不是错误，它只是一个信息日志：https://github.com/emberjs/ember.js/blob/master/packages/ember-application/lib/system/resolver.js#L368-L380

Ember 会告诉您它正在寻找哪些对象以及它找到了哪些对象。并非所有对象都需要实现，具体取决于您要获得的效果。
