This solved the issue of me

but not worked for me got same error

Thanks Dude… you saved my day

FYI In my Ionic v5 project there is a tsconfig.json file and a tsconfig.app.json file, and I had to change the tsconfig.app.json file.

I also had to

npm i buffer --save

and

import { Buffer } from buffer

to fix my specific error which was

Cannot find name 'Buffer'

for those having similar issues

Make sure you downgraded @ionic/app-scripts to 3.2.3 version. You can verify it while run build.

I would be extremely wary of whatever dependency you have that’s needing buffer. That’s a typical hallmark of a library that is not designed to run in browser environments, and the buffer dependency could be the tip of that incompatibility iceberg. I would suggest trying to refactor with an alternative dependency that is not so tightly coupled to running under node.

also, i faced the same issue.
i made as @virtualvishwam described works well with me.

thanks, works fine !!

this worked for me without downgrading other dependencies
