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

Answer 1

You can't start linux without linux.

You can't launch a rackup server without Rack.

You can't launch thin without thin gem.

Answer 2

/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.

Answer 3

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
