Question

在离子应用程序中，所有npm软件包都已删除并使用npm install重新安装。现在运行离子服务显示大约十几个与firebase和angularfire2相关的错误。

要调试，

我已卸载并重新安装angularfire2和firebase
我已经仔细检查了tsconfig.json文件，该文件看起来与错误开始前相同
我重新启动了服务器

然而，仍然没有......

还有一些与不可用的对等依赖关系有关的npm警告，我在下面附上，我不太清楚如何处理...

这是主app的package.json依赖列表：

Answer 1

对于angularfire2版本5.0.0+，不推荐使用FirebaseListObservable和FirebaseObjectObservable。请恢复为4.0.0。+版本

Answer 2

好的，在@alltej的帮助下对此进行故障排除后，看起来我对npm update命令不够谨慎，导致AngularFire2和Firebase npm软件包都升级到版本号发生变化的版本导致一些重大变化。

例如，在整个应用程序中使用的FirebaseObjectObservable已在第5版中弃用。回滚到先前版本解决了问题/

重新安装NPM软件包后，系列的离子/ Firebase AngularFire2错误
