Hi!
I just reinstalled my Mac and checked out my Ionic v1 repo.
If I want to run my project (ionic build android) I have the issue that the “ionic” folder inside “www/lib” is missing. This folder contains the file “ionic.bundle.js”. I do not remember if I added this folder and the containing files by hand or if they had been generated from Ionic. It’s too long ago that I was working on that app 
I have the latest Ionic CLI installed. I used “ionic state restore” to restore my plugins and of course installed all node modules via “npm install”.
Are there any issues / pitfalls I have to take care of regarding an “old” app that uses Angular v1 and the new Ionic CLI?
Thanks for your help!
