Sinatra - cannot load such file -- sinatra/base

[juneira]

When I run: falcon --verbose serve --bind "https://0.0.0.0:3000"

With config.ru:

# frozen_string_literal: true

require 'sinatra/base'
class App < Sinatra::Base
  get "/" do
    "hello"
  end
end

use App
run lambda {|env| [404, {}, []]}

This exception is raised:

 1.53s    error: Async::Container::Process [ec=0xd34] [pid=2467] [2023-10-21 11:59:31 +0000]

(I follow this example)

Do you have the gemfile?

Also did you try running bundle exec falcon ...?
