ionic serve在“node_modules/@angular/core/src/render3/definition.d.ts”中有Typescript Error

Question

我在我的Windows中安装了离子4我的应用程序工作正常，但当我将它降级为离子3时，它一直给我错误。 所以我完全卸载了cordova，ionic和nodejs，并删除了节点缓存并重新安装了所有内容但是当我运行离子服务时，它一直在浏览器中为我之前的每个应用程序提供此错误：

我也尝试删除node_modules并为我的应用程序重新安装所有这些但不起作用。

我有 ：

Ionic Framework: 3.9.2
Ionic App Scripts: 3.2.2
Angular Core: ^7.2.9
Angular Compiler CLI: ^7.2.9
Node: 11.12.0
OS Platform: Windows 7
Navigator Platform: Win32
User Agent: Mozilla/5.0

好吧，你看到没有人回答！ 我不得不建立一个新的应用程序，然后重新开始工作！ 甚至将代码复制到新的应用程序都不起作用！ 其中一个问题是我的节点版本。 我提到它，以防有人有同样的问题，并想尝试解决它。
