【问题描述】：
我在我的 Windows 中安装了 ionic 4，我的应用程序运行良好，但是当我将其降级到 ionic 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东西，但是当我运行ionic serve时，它一直在浏览器中为我以前拥有的每个应用程序提供这个错误：

我还尝试删除 node_modules 并为我的应用重新安装所有这些，但没有奏效。
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
