Ruby 2.4.0 Released, Ruby is a dynamic, object-oriented programming language focused on simplicity and productivity. RVM (Ruby Version Manager) is a tool for installing and managing multiple Ruby versions on single operating systems. This tutorial will help you to install RVM on your system. After that install Ruby 2.4.0 on CentOS, RedHat systems using RVM.
Step 1. Installing Requirements
First of all, we need to install all required packages for ruby installation on our system using the following command.
installgcc-c++ patch readline readline-devel zlib zlib-devel # yum installlibyaml-devel libffi-devel openssl-devel make # yum installbzip2 autoconf automake libtool bison iconv-devel sqlite-devel
Step 2. Install RVM
Install the latest stable version of RVM on your system using the following command. This command will automatically download all required files and install on your system.
# curl -sSL https://rvm.io/mpapis.asc | gpg --import - # curl -L
get.rvm.io| bash -s stable
Also, run below command to load rvm environment.
# source /etc/profile.d/rvm.sh # rvm reload
Step 3. Verify Dependencies
Now use following command to verify all dependencies are properly installed.
rvm requirements runChecking requirements for centos. Requirements installation successful.
Step 4. Install Ruby 2.4
After completing setup of RVM environment lets install Ruby language using the following command.
# rvm install
Searching for binary rubies, this might take some time. Found remote file https://rvm_io.global.ssl.fastly.net/binaries/ubuntu/16.04/x86_64/ruby-2.4.0.tar.bz2 Checking requirements for ubuntu. Requirements installation successful. ruby-2.4.0 - #configure ruby-2.4.0 - #download % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 16.4M 100 16.4M 0 0 724k 0 0:00:23 0:00:23 --:--:-- 790k No checksum for downloaded archive, recording checksum in user configuration. ruby-2.4.0 - #validate archive ruby-2.4.0 - #extract ruby-2.4.0 - #validate binary ruby-2.4.0 - #setup ruby-2.4.0 - #gemset created /usr/local/rvm/gems/[email protected] ruby-2.4.0 - #importing gemset /usr/local/rvm/gemsets/global.gems.............................. ruby-2.4.0 - #generating global wrappers........ ruby-2.4.0 - #gemset created /usr/local/rvm/gems/ruby-2.4.0 ruby-2.4.0 - #importing gemsetfile /usr/local/rvm/gemsets/default.gems evaluated to empty gem list ruby-2.4.0 - #generating default wrappers........
Step 5. Setup Default Ruby Version
First of all, check currently installed ruby versions on your system. So that we can which version is using currently by the system and which is set to default.
rvm listrvm rubies * ruby-2.3.0 [ x86_64 ] ruby-2.3.3 [ x86_64 ] => ruby-2.4.0 [ x86_64 ] # => - current # =* - current && default # * - default
After that use rvm command to setup default ruby version to be used by applications.
rvm use 2.4.0 --defaultUsing /usr/local/rvm/gems/ruby-2.4.0
Step 6. Check Current Ruby Version.
Using following command you can check the current ruby version is used.
ruby --versionruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux]
