If I create a new project with require_reloader

rails new lala

and I'm creating a gem with a dash in its name, let's say:

bundle gem foo-bar

then load the gem changing the Gemfile like:

gem 'foo-bar', path: '../foo-bar'

it throws:

/home/alter/.rvm/gems/ruby-2.4.2@default/gems/activesupport-5.1.4/lib/active_support/dependencies.rb:292:in `require': cannot load such file -- foo-bar (LoadError)

Same issue, blocks all my gem loading as they're prefixed with a namespace

If you are working with your gem locally and can modify it then you can change autoload_paths for your gem inside gem:

#/lib/mygem.rb
module OurGem
  if defined?(Rails)
    require 'mygem/engine'
  else
    require 'mygem/mystuff'
  end
end
#/lib/mygem/engine.rb
module Mygem
  class Engine < ::Rails::Engine
    config.autoload_paths += Dir["#{config.root}/lib/**/"]
  end
end

In my case my gem was a simple gem which can be used without Rails.
I tried to add gem's directories to autoload_paths and it didn't work.
Even I added my paths directly

mygem_base_path = '/local/path/to/gem/lib'
config.autoload_paths += Dir[mygem_base_path]
config.autoload_paths += Dir[File.join(mygem_base_path, "**/"]
