Issue launching ruby on rails in static.rb file

Question

I am trying to deploy a ruby on rails app on heroku so I updated my ruby version to ruby 3.0.0 and did bundle update / bundle install but it says I can not push and not even run a local development server.


=> Booting Puma
=> Rails 5.1.7 application starting in development 
=> Run `rails server -h` for more startup options

The static.rb file in question:

module ActionDispatch
...
  class Static
    def initialize(app, path, index: "index", headers: {})
      @app = app
      @file_handler = FileHandler.new(path, index: index, headers: headers)
    end

    def call(env)
      req = Rack::Request.new env

      if req.get? || req.head?
        path = req.path_info.chomp("/".freeze)
        if match = @file_handler.match?(path)
          req.path_info = match
          return @file_handler.serve(req)
        end
      end

      @app.call(req.env)
    end
  end
end

ruby version: ruby 3.0.0p0

rails version: Rails 5.1.7

gem version: 3.2.12

Can you help me out?

In log, it is showing the rails version as 5.1.7. But you have mentioned it as 6.1.3.? — sgk, Mar 02 '21 at 07:43
I had both installed. I uninstalled the 6.1.3 but no change... sorry for the confusion. — Dimitri, Mar 02 '21 at 08:02
There is already another question related to this. Please check. https://stackoverflow.com/questions/9087116/which-ruby-on-rails-is-compatible-with-which-ruby-version. Either u need to reduce your ruby version or increase the rails version. — sgk, Mar 02 '21 at 08:17
Does this answer your question? [Which Ruby on Rails is compatible with which Ruby version?](https://stackoverflow.com/questions/9087116/which-ruby-on-rails-is-compatible-with-which-ruby-version) — Jaffa, Mar 02 '21 at 08:31
Yes ! I updated rails by changing the gemfile with gem 'rails', '~> 6.1.3' and did bundle update and it works. Thank you ! — Dimitri, Mar 02 '21 at 09:02

ruby 2.7+ support is only available starting from rails 6, so you'll need to either downgrade ruby, or upgrade rails
