Getting an old ionic app to run?

I’ve got an app written in 2015 (I’m not sure which version of ionic?)

I’ve loaded it onto a machine that has ionic v3 on it. I’m wondering if I can run it even though it’s not written in typescript?

I tried making a few changes to the config file per this stack overflow article and adding some of the files from a newer ionic project to it, but I get this error. Any suggestions would be greatly appreciated.

Article I followed ->

Error stack I get:
