与 forum.ionicframework.com 相同的问题

首先，我不在我的项目中使用类型。至少我所知道的不是。我也不使用 localforage，但它是 @ionic/storage 的依赖项。我确实安装了 Typings 和 localforage 希望解决这个问题，但它并没有解决它，而且可能还有残留。

这是我不断收到的错误

这是输出ionic info

也许有趣的是，每当我尝试时，ionic cordova build android我都会遇到这个问题

[INFO] Looks like @ionic/app-scripts isn't installed in this project.

       This package is required for this command to work properly.

? Install @ionic/app-scripts? (Y/n)

显然我已经安装了应用脚本。

另一件可能需要注意的重要事情是，当我运行ionic cordova prepare --no-build脚本时停止在Preparing Firebase on Android，不确定这是否是故意的，或者如果 firebase 以某种方式停止准备脚本。

我使用ionic start、 运行npm install然后ionic serve. 遇到了同样的问题。我没有在我的项目中使用 localforage，我真的不知道该怎么做。谷歌也没有给出答案。

完全重新安装 Node 后，此问题消失了。我不知道什么是损坏的，如果重新安装是唯一的解决方案，但它为我解决了它。
