cannot load such file -- webrick/httputils - ruby-on-rails

Question

I have a project I'm trying to use ruby 3 (previously running with 2.7.2), but couldn't accomplish it.
After updated my gemfile with the ruby version and ran bundle, I'm receiving this error when trying to access rails c:
/home/rwehresmann/.rvm/gems/ruby-3.0.0/gems/bootsnap-1.5.1/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:23:in `require': cannot load such file -- webrick/httputils (LoadError)
I already tried to add webrick gem to see what happens, and the result is that rails c get stuck.
Here is my gemfile:

Any suggestions?

Answer 1

You have spring in your gemfile, usually hanging consoles and servers are related to that. The webrick gem was removed from the standard library in Ruby 3, so that's why it needs to be included in your Gemfile.
Add webrick to your Gemfile, do a bundle install, and then stop the background spring server with bin/spring stop. Then re-run the server.
Your best bet on solving issues with spring would be to head over and read about the gem on the GitHub project page, or opening a new question here on SO.

Answer 2

Try:
bundle add webrick
Adding gem "webrick" to Gemfile solves the problem.
