Starting thin server without the thin gem does not work

Question

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

/home/rzaartz/.rvm/gems/ruby-1.9.3-p125/gems/rack-1.4.1/lib/rack/handler/thin.rb:1:in `require': cannot load such file -- thin (LoadError)

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 – Uchenna Mar 05 '12 at 20:05
but he had thin install on this gem repository – shingara Mar 05 '12 at 20:06
`rackup -rubygems private_pub.ru -s thin -E production` and you need stop using Bundler – shingara Mar 05 '12 at 20:22
still no luck unless i add the thin gem in my gem file – Uchenna Mar 05 '12 at 20:29

@UchennaOkafor Then just add it to the Gemfile! Why are you trying to complicate things that are straight forward? – yagooar Apr 30 '13 at 09:45
It's related to the thin upgrade to 1.4.1 (https://github.com/macournoyer/thin/issues/115). This is probably why it works for the old Railscast but not now. – ronan_mac Jan 03 '16 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. – Eric Wanchic Nov 07 '13 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
