Installing Ruby on Ubuntu

Step 1 Verifying

Verify the system is update and then run a sudo apt-get update on the terminal.

Step 2 Installing RVM on Ubuntu

Open terminal and type
  • curl https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer | bash -s stable
This will install RVM on your system.
Please close and open the terminal again to load RVM.
To verify the RVM installation , open Terminal and type
  • rvm requirements
This will show a help doc.

Step 3 Installing required RVM packages before installing Ruby

Open Terminal and run the below mentioned commands one after the another
  • rvm pkg install zlib
  • rvm pkg install openssl
  • rvm pkg install iconv
  • rvm pkg install readline
  • rvm pkg install autoconf

Step 4 Installing Ruby

Open the Terminal and type the following command
  • rvm install 1.8.7 -C --with-openssl-dir=$rvm_path/usr --with-zlib-dir=$rvm_path/usr
Here 1.8.7 reflects the Ruby version 1.8.7 and the latest patch, so to install any specific version or path you specify it by altering the above mentioned command eg.
  • rvm install 1.8.7-p334 -C --with-openssl-dir=$rvm_path/usr --with-zlib-dir=$rvm_path/usr
  • rvm install 1.9.3 -C --with-openssl-dir=$rvm_path/usr --with-zlib-dir=$rvm_path/usr

Step 5 Verify the installation

Open a new Terminal window and type
  • rvm list This will display the list of the different rubies installed on the system.
    To use a specific Ruby version use the following command
  • rvm use 1.8.7
  • rvm use 1.8.7-p334
  • rvm use 1.9.3 To make a Ruby version default for the system use the command
  • rvm alias create default 1.8.7
  • rvm alias create default 1.8.7-p334
  • rvm alias create default 1.9.3
This Ruby version will be the default version of Ruby on the system , to change to other versions of Ruby use the above mentioned commands.
To use default incase of switching use
  • rvm use default
To remove RVM from the system use the command
  • rvm implode
