how to install a ruby version with rvm when you are offline

This has happened to me manytimes, When I try to install a version of ruby, rvm crashes unable to download the right version of the ruby source code. Sometimes because it can't resolve rubyforge.org and other times for other reasons.

Anyway, when such a thing happens, or when you don't have an internet connection to the computer on which you want to install a version of ruby, you can copy the zipped file with the source code to your $HOME/.rvm/archives/ directory and then run rvm install <ruby-version>. This will install the desired ruby version skipping the download and using the file present in the archives direcotry.

cp ruby-enterprise-1.8.7-2010.02.tar.gz /home/minhajuddin/.rvm/archives
rvm install ree-1.8.7
