离子错误：没有导出的成员OpaqueToken

Question

我有一个工作正常的Ionic项目，但是当我尝试安装angular-fire（在特定分支上）时，我不得不更新一些软件包，现在应用程序无法正常工作。我有几个Typescript错误，如：

node_modules/ionic-angular/config/config.d.ts, line: 1 Module '"/Users/toto/Desktop/myProject/node_modules/@angular/core/core"' has no exported member 'OpaqueToken'.

我在特定分支中进行了所有更改。但是当我切换到较旧的分支时，错误仍然存​​在。 我试过npm install --save-dev @angular/cli@latest（版本6.0.0）。离子版本是3.20.0。

我不在任何地方使用OpaqueToken，我不知道为什么我会这样做。我检查了几个github问题或SO问题，但没有什么对我有用。

这是我的package.json：

有人有这个问题吗？

修改

按照以下建议更新我的软件包后，出现此错误：

我不在任何地方使用SubscriptionLike。我试图评论任何rx导入，但它没有改变任何东西..

您应该将所有内容更新为新版本的Angular（6.0）。

请参阅https://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_video_autoplay。

我认为你的Typescript版本应至少为2.7.2，angular core 6.0，rxjs 6.1和ionic latest。

修改：安装official update guide for details模块以解决兼容性问题。阅读RxJS部分rxjs-compat以了解原因：基本上RxJS6改变了导入它的成员的方式。
