In this tutorial I am going to show you , How you can Install Ruby via two different methods First by using source and Second Via RVM .
why we are using these two methods :
Simple we want to install latest version
if you are installing via
apt-get method most of the chances are that it wont install latest version just because according to ruby-lang.org
Certain members in the Ruby community feel very strongly that you should never use a package manager to install Ruby and that you should use tools instead. While the full list of pros and cons are outside of the scope of this page, the most basic reason is that most package managers have older versions of Ruby in their official repositories. If you would like to use the newest Ruby, make sure you use the correct package name, or use the tools described above instead.
These Steps are tested on Ubuntu 14.04
I do not issue any guarantee that it will work for you , Please leave comment if you face any problem ,
Okay ,Lets get Started
sudo apt-get update sudo apt-get install gawk g++ gcc make libc6-dev libreadline6-dev zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 autoconf libgdbm-dev libncurses5-dev automake libtool bison pkg-config libffi-dev
Installing Via Source
Open terminal and type
It will download the source
tar to extract the tarball ..
tar -xvzf ruby-2.1.1.tar.gz
Now change directory to
now compile and install
./configure make sudo make install
wait until it finish installing .
after installation type
ruby -v which ruby
it will print version number and binary location info .
Installing Via RVM (Recommended )
sudo apt-get update sudo apt-get install curl git-core -y
Now Lets install RVM first
\curl -sSL https://get.rvm.io | bash -s stable source $HOME/.rvm/scripts/rvm
now restart your terminal and lets test rvm installation
type rvm | head -n 1
if it returns
rvm is a function it means things are working correct .
okay, Lets install ruby ,
If you want to see list
rvm list known
Lets install ruby
rvm install ruby-2.1.1
it will take some time and install ruby 2.1.1 for you
Okay Lets tell rvm to use that ruby
rvm use 2.1.1 --default
now again test ruby version and binary location
ruby --version which ruby
It will show you version number and binary location
Happy Coding ….
