I’ve gotten a warning from npm
npm WARN read-shrinkwrap This version of npm is compatible with lockfileVersion@1, but package-lock.json was generated for lockfileVersion@2. I’ll try to do my best with it!
It would be my guess that I am using a later version of npm on my PC (where I developed the app) than is running on Glitch. Is there a) a way to confirm that b) a way to update npm? Or for that matter c) am I mistaken?
