I’ve previously installed ruby 1.8.7 on my system. Some time late I installed rvm. Since then there’s a giant mess. For example trying to bring up a Sinatra server results in:

/home/yoni/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find rack (>= 0) amongst [bundler-1.1.3, faraday-0.8.4, koala-1.5.0, multi_json-1.3.6, multipart-post-1.1.5, rake-0.9.2.2, rubygems-bundler-0.9.0, rvm-1.11.3.3] (Gem::LoadError)

I know this is the result of having two ruby installations and therefore two location for gem files but I’m not sure how to fix this. I don’t mind removing ruby 1.8.7 entirely, but I’d like to do it without breaking anything.

Any ideas?

Update: result of dpkg --get-selections | grep ruby is:

    apt-get --purge remove packagename

    from all of the things that show up from dkpg --list | grep ruby that are not on the list below:

    From rvm requirements

    Additional Dependencies:
# For Ruby / Ruby HEAD (MRI, Rubinius, & REE), install the following:
  ruby: /usr/bin/apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion pkg-config

    If it isn’t possible from CLI, use synaptic package manager:
