Can't install sinatra-contrib

I am trying to run a simple application with Sinatra and I am not able to install the reloader.

I tried with

gem install sinatra-contrib

and I have in my source file a line like this:

require "sinatra/reloader" if development?

and in my Gemfile

gem "sinatra-contrib", "~> "1.3.1"
gem 'sinatra-reloader'

and I get an error while trying to start the gem install sinatra-config

>gem install sinatra-contrib

ERROR:  Error installing sinatra-contrib:
    ERROR: Failed to build gem native extension.

    C:/Ruby192/bin/ruby.exe extconf.rb

checking for rb_trap_immediate in ruby.h,rubysig.h... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.`

I can't figure it out. And if I have the require "sinatra/reloader" if development? line, it just won't work. There are not many things on the web about this. I know shotgun is not an option in Windows.

I've had this error once. Here is the gist, check the comments under that. Basically, sinatra-contrib depends on event machine which is not good for Windows. Remove that dependency or install event machine
