So I just had this disconcerting moment of weirdness:

	❯ rvm use 3.1.0
	Using /Users/sjohnson/.rvm/gems/ruby-3.1.0

	coding/rails/cartazzi via  v18.2.0 via 💎 v3.1.0 on ☁️  (us-west-2)
	❯ ruby -v
	ruby 3.1.0p0 (2021-12-25 revision fb4df44d16) [x86_64-darwin19]

	coding/rails/cartazzi via  v18.2.0 via 💎 v3.1.0 on ☁️  (us-west-2)
	❯ bundle exec rails c
	Your Ruby version is 2.6.3, but your Gemfile specified 3.1.0

What's going on here is:

  1. I clearly told the system what ruby to us.
  2. I verified it.
  3. It told me "OH HELL NO"!

This took more than a moment of head scratching and then I hit on it:

bundle install

And, after that completed:

	coding/rails/cartazzi via  v18.2.0 via 💎 v3.1.0 on ☁️  (us-west-2)
	❯ bundle exec rails c
	Loading development environment (Rails 7.0.2.2)
	3.1.0 :001 >
