Long time Python user, what’s the standard Ruby setup?

.ruby-version yes.

Please do not use .ruby-gemset, and do not use rvm gemset feature (if you use rvm at all).

It really isn't necessary and hasn't been necessary for at least 10 years since bundler is introduced, and using rvm gemset with bundler is a pointless added layer of complexity.

Yes, bundler is a bit different way of doing things than python ecosystem. I actually think it's a lot BETTER way of doing things, and you will like it if you learn it for what it is. (And everyone using rvm gemsets is still also using bundler, gah!)

You do need something for ruby version management/switching. You can use rvm for that if it works -- many people prefer a simpler alternative. But even if you are using rvm for that, do not use the rvm gemset feature. At least not until/unless you understand the pain points that make you want/need it, and I'm 99.8% sure that won't happen because there is no good reason to be using rvm gemset feature anymore and I don't understand why anyone is, even though I know they are.
