I'm using macbook for programming, and I got an upgrade notice, but after upgrading my macbook to the newest version, I can't start the rails server anymore. I get these errors when I run rails s. The version I'm using is macOS Catalina version 10.15.4

Got it working by installing nodejs

I experienced the same issue and could resolve it by installing nodejs version 12.18.0 for OS X from nodejs.org on my MacBook
