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

Question

我在我的Windows中安裝了離子4我的應用程序工作正常，但當我將它降級為離子3時，它一直給我錯誤。 所以我完全卸載了cordova，ionic和nodejs，並刪除了節點緩存並重新安裝了所有內容但是當我運行離子服務時，它一直在瀏覽器中為我之前的每個應用程序提供此錯誤：

我也嘗試刪除node_modules並為我的應用程序重新安裝所有這些但不起作用。

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，你看到沒有人回答！ 我不得不建立一個新的應用程序，然后重新開始工作！ 甚至將代碼復制到新的應用程序都不起作用！ 其中一個問題是我的節點版本。 我提到它，以防有人有同樣的問題，並想嘗試解決它。
