Installing on Linux is a little difficult but do-able, first off download the Linux build and extract it.

Next up you'll need to add an environment variable into your .bashrc file,

gedit .bashrc

Then add this to the end of the file, with the path of your JAVA JDK location.

export JDK_HOME=/usr/lib/jvm/java-6-openjdk/

Save it and reload Terminal so it's got the new variable, then in Terminal navigate into the bin directory of RubyMine you just downloaded,

cd ~/Desktop/rubymine472/bin

Then remove the last line of rubymine.vmoptions

gedit rubymine.vmoptions

  remove this line => -agentlib:yjpagent=disablej2ee,sessionname=rubymine

Once done you should be able to start up RubyMine;

~/Desktop/rubymine472/bin/rubymine.sh

Then you can add it to your .bashrc file so you can fire it up any time you want with an alias,

alias rubymine="~/Desktop/rubymine472/bin/rubymine.sh"

And then

rubymine
