聚合物1.x + Firebase ==你好世界？ [英] Polymer 1.x + Firebase == Hello world?
问题描述
我想用Polymer firebase-collection 元素制作 Hello，world 。 b
$ b
我希望看到一个或多个 Hello，world 的重复，并且在控制台中没有错误。相反，我没有看到 Hello，world 和许多以下列开头的控制台错误：
console.log
ReferenceError：未定义Firebase
重新创建问题，请按照下列步骤操作：
- 打开这个jsBin 。
- ❌观察不到 Hello，world 和控制台中的错误。
请注意，< firebase-collection> 代码仅仅是复制/粘贴来自位于此处的官方文档。

这个问题是由服务器问题（在polygit2.appspot.com ）现在已经解决了。
I want to make Hello, world with the Polymer firebase-collection element.
I expect to see one or more repetitions of Hello, world and no errors in the console. Instead, I see no Hello, world and many console errors beginning with:
ReferenceError: Firebase is not defined
To recreate the problem, follow these steps:
- Open this jsBin.
- ❌ Observe no Hello, world and errors in the console.
Notice the <firebase-collection> code is simply a copy/paste from the official documentation located here.
