When I run the command fly console , I encounter the error: “uninitialized constant IRB (NameError)” .

logs:

➜ fly  console

fly config:

console_command = './bin/rails console'

[deploy]
  release_command = "./bin/rails db:prepare"

[processes]
  web = "./bin/rails server"

Can you describe how you are vendoring Rails?

I tried:

rails new demo-24112
cd demo-24112
echo 'Rails.application.routes.draw { root "rails/welcome#index" }' > config/routes.rb
bin/rails generate dockerfile --force --jemalloc --fullstaq
fly launch
fly deploy
fly console

And this worked for me. With Ruby 3.3.0, fullstaq, and jemalloc. The one difference I can spot is that you have a /rails/vendor directory and I do not.

I’m experiencing the same issue. And looking at my error message, I don’t have a /rails/vendor directory, so I don’t think it’s related.

I believe that’s something new. I started seeing this problem today in a DO server. Investigating where the error originated. Any ideas?

I tried:

  1. update ruby (to 3.3.0), didn’t work
  2. dowgrade Rails (to 7.1.2), didn’t work

I’m trying now uninstall the latest gems.

Adding gem “irb” in the Gemfile fixes for me
