【问题描述】：

将 Ionic CLI 更新到 4 后，我尝试运行的每个命令都不起作用。

例如：

Ionic serve,
ionic cordova build android
ionic cordova run android
ionic cordova build ios
...

我收到这样的错误：

Looks like @ionic/v1-toolkit isn't installed in this project.

然后我尝试按照他们的要求安装软件包：

? Install @ionic/v1-toolkit? Yes
> npm i -D -E @ionic/v1-toolkit

但我得到以下错误作为回报：
