Same question as forum.ionicframework.com
首先，我不在项目中使用打字。至少我不知道。我也不使用localforage，但这是@ ionic / storage的依赖项。我确实安装了打字程序和localforage以希望解决此问题，但并不能解决问题，因此可能还会有残留。
这是我不断收到的错误

这是ionic info

[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。
需要注意的另一件事是，当我运行ionic cordova prepare --no-build时，脚本在Preparing Firebase on Android处停止，不确定这是否是预期的，或者firebase是否以某种方式停止了prepare脚本。

我使用ionic start创建了一个新的空白项目，先运行npm install，然后运行ionic serve。有同样的问题。
我在项目中没有使用localforage，我真的不知道该怎么做。 Google也没有给出答案。
答案 0 :(得分：0)
完全重新安装Node后，此问题消失了。我不知道什么东西损坏了，如果重新安装是唯一的解决方案，但是它为我解决了。
