I am so sorry,I just want to describe the problem more detail,sorry
ionic.project file. I think this was renamed. I think this was renamed ionic.config.json. Try renaming that file and run ionic info again.Also after renaming the ionic.project try installing the Ionic cli plugin for ionic1. I had to do this manually previously, however the most recent Ionic CLI offered it to me.
npm install --save-dev @ionic/cli-plugin-ionic1@latest
HTH
Yep, CLI should offer that on running ionic info when the file is present - so no need to execute that line manually.
