I seem ionic-app-scripts is too old. ( recent version is ionic-app-scripts 3.1.8 )

You should do ionic docker check.

Thanks @peterennis, I launched RC.0 without the automatic installation due to some dependency issue I don't remember. 😆 I'll add it back for the next RC.

In the meantime, try this: npm i @ionic/lab@rc npm i @ionic/lab 🎉

@peterennis Please test the behavior in the latest RC release and let me know what you think. Thanks!

I had similar issues and solved it with the code of dwieeb.Thanks!

[franciscojsc]

It worked with the command npm i @ionic/lab@rc @dwieeb

Yep, but that was in March. The CLI is no longer in RC. Please make sure all packages are up to date.

npm i -g ionic
npm i @ionic/lab
