Answer 1

Confirming above answer works.

First I forced it to download the newest eventmachine using the following command:

gem install eventmachine --pre

I added the following line to my gemfile:

gem 'eventmachine', '1.0.0', :platforms => [:mswin, :mingw]

Then found and edited my gemfile.lock with the following lines:

rake (10.1.0) #
## eventmachine (1.0.0)
eventmachine (1.0.0-x86-mingw32)

Then reran bundle install, and all was well. Hope this helps you!

Answer 2

You can write in your Gemfile:

gem 'eventmachine', '~> 1.0.0.beta.4.1'

and run bundle install again, if you have some error about that you're requesting for another eventmachine version and there is a bundle currently gem of eventmachine, you can remove the "Gemfile.lock" and run bundle install again (although it's not good to do, but it worked for me)

PD: I hope this solution works for you too.
