Twitter Bootstrap Question posted in

Trying to deploy Rails App with Capistrano to Do Droplet-Twitter bootstrap

I would like to deploy my app on my server and use capistrano. However, I come across the following error(s) again and again and don’t know how to fix it. First the error was that he couldn’t find Yarn or something was wrong with the Yui Compressor i guess, i think cant file or something like that. Then i installed Yarn on my terminal and the error changed to this one: 

Caused by:

    It looks like a gem you’ve included in your application has a dependency on java. From the ruby-yui-compressor homepage:

    Because YUI Compressor’s .jar file is included in the box, Java >= 1.4 is its only dependency.

    Essentially you need to install java on your server or, if it is already installed, make it available to your deploy user.
