How to install bundler gem on Hetzner server?

Question

I am trying to install bundler using the following command:

gem install bundler

but recieve this error:

ERROR:  could not find gem bundler locally or in a repository

Running command

gem list --local

shows me empty list and

gem sources

shows this:

http://gems.rubyforge.org/
http://rubygems.org/
http://gemcutter.org

I was trying to find the similar problem for an hour, but seems to me that I am not understanding some basic principles to make correct google search query.

What Linux distribution are you using? How is Ruby packaged, is it a package from a distribution repo? Basically I recommend you to try RVM, it is a popular and a convenient way to manage Ruby setups in a distribution-agnostic way. I always use RVM and never have problems like this.
