Newbie Question : Installation Problem


I hope you are doing well,

I just start the course, but I already face a problem :

=> ruby 3.0.0 => Rails

I just bought a course to learn Ruby on Rails, but I am facing a problem with the installation.

I followed this guide : Getting Started with Rails — Ruby on Rails Guides to install Ruby correctly but when I enter the command “rails server” in my Terminal, here is what I get :

@MacBook-Pro-de-Thomas omruby % rails server => Booting Puma => Rails application starting in development => Run bin/rails server --help for more startup options Exiting /Users/thomas/.rvm/gems/ruby-3.0.0/gems/webpacker-5.4.2/lib/webpacker/configuration.rb:103:in `rescue in load’: Webpacker configuration file not found /Users/thomasnurit/omruby/config/webpacker.yml. Please run rails webpacker:install Error: No such file or directory @ rb_sysopen - /Users/thomasnurit/omruby/config/webpacker.yml (RuntimeError)

Also, I don’t have access to localhost : 3000 (impossible to connect to the website),

An idea about what’s happening here ?

Thank you for your feedback,


From your error message. – H
