Install ROR on Ubuntu

Install ruby on Ubuntu

1. First we have to make sure that we have some dependencies installed, so run the following command to take care of them.
  
  sudo apt-get install build-essential git-core
  
2. Now we need to install RVM (Ruby Version Manager) using curl. If you do not have curl installed yet on your system, you can issue the following command
  
  sudo apt-get install curl

3. To start the RVM installation run the following command
  
  bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
  
4. Now we need to add a line to our bashrc file so run the following command

  echo '[[ -s "/home/username/.rvm/scripts/rvm" ]] && source "/home/username/.rvm/scripts/rvm"' >> ~/.bashrc

5. Now run

  source ~/.bashrc

6. To test if our installation of RVM was succesfull, we can run a command and check its output. 
  
  type rvm | head -1

  If the output of the above command is equivalent to rvm is a function, then we now have a working RVM installation

7. Run command as login shell
  
  gedit ~/.bash_profile
    
    source ~/.profile
    source ~/.bashrc
