我一直在使用angular2快速入门代码来构建基本的待办事项应用。
我希望添加一个登录页面和连接到firebase来存储和检索todo，但是firebase3实现有问题。
我可以通过删除启动脚本中的 tsc 调用来实现它（如下所示），但这似乎是一个短期修复。
"start": "concurrently \"npm run tsc:w\" \"npm run lite\" "
当我运行 npm start 时我得到的错误说它无法在我的component.tsc文件中使用它时找到名称firebase。我也注意到我还没有找到firebase 3全局打字下载，所以只有firebase 2打字。
firebase 2和3的布局如何（firebase 3仅在index.html中，而firebase 2似乎在整个声明中）可能导致问题???
请注意我的firebase体验非常有限，所以我可能会误读fb2和fb3之间的区别。
下面是我目前得到的错误 npm start
> angular2-quickstart@1.0.0 start /Users/ahiggins/Documents/angular_2/tutorials/todo
> tsc && concurrently "npm run tsc:w" "npm run lite"
