Updating ionic v1 app with latest cli

I have an old ionic v1 app which needs some updates. The problem is that the gulp is now no more used so I keep getting this error:

 Cannot load gulp: Error: `libsass` bindings not found. Try reinstalling `node-sass`?
[11:34:57] Cannot run sass task: missing in gulpfile.js

I tried installing node-sass but it is throwing new errors. Is there anyways I can update the app now?

Did you end up finding a fix for this?

No, i have since abandoned the project. But what needs to be done is port v1 code without npm dependency and use --v1 flag in latest cli. Probably thart will work.
