Angular 2 AOT - “未捕获的 ReferenceError：导出未定义错误”

Question

我有运行角2应用程序编译AOT使用汇总说明从angular.io文档问题（链接在此）

据我所知，编译过程进行得很顺利，尽管我将其作为唯一的输出：

??   'default' is imported from external module 'rollup' but never used

'initializeApp' is not exported by 'node_modules/firebase/firebase-node.js'
'initializeApp' is not exported by 'node_modules/firebase/firebase-node.js'
'app' is not exported by 'node_modules/firebase/firebase-node.js'
'auth' is not exported by 'node_modules/firebase/firebase-node.js'
'database' is not exported by 'node_modules/firebase/firebase-node.js'
'database' is not exported by 'node_modules/firebase/firebase-node.js'

该build.js创建和我有我的index.html指向它和其他所需的文件：

??   'default' is imported from external module 'rollup' but never used

'initializeApp' is not exported by 'node_modules/firebase/firebase-node.js'
'initializeApp' is not exported by 'node_modules/firebase/firebase-node.js'
'app' is not exported by 'node_modules/firebase/firebase-node.js'
'auth' is not exported by 'node_modules/firebase/firebase-node.js'
'database' is not exported by 'node_modules/firebase/firebase-node.js'
'database' is not exported by 'node_modules/firebase/firebase-node.js'

但是，当我在浏览器中运行我的应用程序时，我得到Uncaught ReferenceError: exports is not defined。

关于如何解决它的任何建议？
