Solved ruby-on-rails ruby-on-rails-3 ruby-on-rails-3.1 thin faye

I am using ruby 1.9.3 and rails 3.2.2. Every time i use the thin server with private_pub gem it does not work i did rackup private_pub.ru -s thin -E production. I get the following error

You can't start linux without linux.

You can't launch a rackup server without Rack.

You can't launch thin without thin gem.

i checked a tutorial by ryan bates and in his source code he did not include the thin gem – Ceratodus 5/3, 2012 at 20:5

but he had thin install on this gem repository – Electrophoresis 5/3, 2012 at 20:6

rackup -rubygems private_pub.ru -s thin -E production and you need stop using Bundler – Electrophoresis 5/3, 2012 at 20:22

still no luck unless i add the thin gem in my gem file – Ceratodus 5/3, 2012 at 20:29

@UchennaOkafor Then just add it to the Gemfile! Why are you trying to complicate things that are straight forward? – Hannelorehanner 30/4, 2013 at 9:45

It's related to the thin upgrade to 1.4.1 (github.com/macournoyer/thin/issues/115). This is probably why it works for the old Railscast but not now. – Selfknowledge 3/1, 2016 at 20:52

/home/dimas/RUBY/application/faye-tutorial/faye.ru:3:in `require': cannot load such file -- thin (LoadError)
    from /home/dimas/RUBY/application/faye-tutorial/faye.ru:3:in `block in <main>'

I have the same problem. fix it with:

add this gem to Gemfile

gem 'faye'
gem 'thin'

then bundle install.

Many who find this are probably using Rails 4 / Ruby 2, and following Ryan Bate's railscast #260 on faye. $ rackup faye.ru -s thin -E production He doesn't have faye or thin in the gem file. Despite doing a gem install on both faye and thin, @ least for Rails 4, faye & thin need to be in the gem file and a bundle install executed before the server will start. – Plante 7/11, 2013 at 13:32

If you want to use a gem, it must be in your Gemfile. You can solve your problem as follows:

Add the following line to your Gemfile: gem 'thin'
Update your current app's environment: bundle install
Start the web server: bundle exec thin start
