Question

我正在使用Angular 2 app来存储用户在firebase中的购买详情。我正在使用AngularFire2与firebase进行交互。该项目工作正常，直到我更新了angularfire2库。他们在github回购中提到他们在AngularFire 5.0进行了一些重大更改。我尝试更新documentation中提到的函数调用。

我仍然收到以下错误。

我的package.json文件是：

Answer 1

我有同样的问题，只是通过更新angularfire2来解决它。你仍然是版本4.0.0.rc0（我是rc2）。我已更新到最新版本5.0.0-rc.1，所有错误都消失了。

运行：

npm uninstall angularfire2

然后：

npm install angularfire2 --save

Answer 2

我遇到了同样的问题并修复了app.module.ts IMPORTS。

你能告诉我你的app.module.ts档案吗？

Answer 3

也许尝试降级到

“angularfire2”：“^ 4.0.0-rc.0”， “firebase”：“^ 3.9.0”

在package.json中的

- 这在我的项目中对我有用。
