【问题标题】：Cannot find module '@angular/core' + ionic 3找不到模块'@angular/core' + ionic 3
【发布时间】：2018-10-08 13:50:23
【问题描述】：

angular/core 实际上是在正确的位置。这是我第一次面对这个问题。这种情况该怎么办？

我已经开始遇到与 FCM（Firebase 云消息传递）集成的问题

这是我的 package.json

添加 "angularfire2": "^5.0.0-rc.6.0", 同样的错误：无法复制这个是离子输出

所以，我降级了

来自：

 "angularfire2": "^5.0.0-rc.6.0"

到：

"angularfire2": "5.0.0-rc.3",

与，

来自：

"firebase": "^4.13.1",

到：

  "firebase": "^4.6.0",

【问题讨论】：

确切的错误日志是什么？
我已更新问题以包含运行“ionic cordova run browser”和“ionic serve”时的错误日志。谢谢
看起来 angularfire2 正在抛出它.. 哪个版本？我在 package.json 中没有看到它
另外请将错误日志粘贴为文本而不是图像
我想你要找的是github.com/angular/angularfire2/issues/1385

【解决方案1】：

感谢 Suraj Rao 的评论，您可以在这里找到问题的解决方案： “FirebaseApp 未正确实现” 如下图所示

更多详情请参考本帖：:github.com/angular/angularfire2/issues/1385

回滚到"firebase": "4.8.0" 有助于解决上述问题
