How to find and install latest Ruby version using RVM?

1

I finally got RVM working and now I would like RVM to install the latest stable ruby version.

In the tutorial I am using they installed ruby 1.9.3 with command :

rvm install 1.9.3

Now I want to know if there is a command to download the latest stable version, or do I have to check latest stable version and download it like that, or else, can I download any old version and run an upgrade?

Normally I would try out everything, but I am working on a new server and I am trying to set it up as clean as I can :)

you can install latest rvm and ruby by :

$ \curl -L https://get.rvm.io | bash -s stable --ruby

and check all the ruby version with stability

$ rvm list known

can also check details here : http://www.ruby-lang.org/en/downloads/

$ rvm install ruby 2.0.0-p247

Use when you want to download specific version or know this is stable.

The following command will install latest stable version of ruby:

rvm install ruby --latest

First update RVM:

rvm get stable

Then update your Ruby version:

rvm upgrade 2.0.0

Choose yes for all the questions:

Are you sure you wish to upgrade from ruby-2.0.0-p195 to ruby-2.0.0-p247? (Y/n): Y Are you sure you wish to MOVE gems from ruby-2.0.0-p195 to ruby-2.0.0-p247? This will overwrite existing gems in ruby-2.0.0-p247 and remove them from ruby-2.0.0-p195 (Y/n): Y Do you wish to move over aliases? (Y/n): Y Do you wish to move over wrappers? (Y/n): Y Do you also wish to completely remove ruby-2.0.0-p195 (inc. archive)? (Y/n): Y

If you wish to update your gems to the latest versions, you can do:

rvm all do gem update

EDIT: I just did this today for the latest version of ruby 2.0.0 (I updated from ruby-2.0.0-p195 to ruby-2.0.0-p353). After that, I was getting segmentation fault when I tried to update gems. This happens because the gems were installed for ruby-2.0.0-p195 and some of them are incompatible with p353.

Now you can go and try to...

Ruby is popular programming language among a large number of developers. Rails are the framework to run ruby language. Ruby language was created by Yukihiro “Matz” Matsumoto and first published in 1995. This article will help you to install ruby on rails on Ubuntu, Debian and Linuxmint operating systems using RVM. RVM is the Ruby Version Manager helps for installing and managing Ruby language on systems.

Step 1 – Install RVM

First of all, 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.

Install CURL apt-get install curl

Install RVM

Before installing RVM first we need to import public key in our system then use curl to install rvm in our system.

curl -sSL https://rvm.io/mpapis.asc | sudo gpg2 --import - curl -sSL https://get.rvm.io | sudo bash -s stable

After installing RVM first we need to set up rvm...

Introduction

Ruby on Rails is one of the most popular application stacks for developers looking to create sites and web apps. The Ruby programming language, combined with the Rails development framework, makes app development simple.

You can easily install Ruby and Rails with the command-line tool RVM (Ruby Version Manager). RVM will also let you manage and work with multiple Ruby environments and allow you to switch between them. The project repository is located on GitHub.

In this guide, we'll install RVM on an Ubuntu 16.04 server, and then use that to install a stable version of Ruby and Rails.

Prerequisites

This tutorial will take you through the Ruby on Rails installation process via RVM. To follow this tutorial, you need an Ubuntu 16.04 server with a non-root user.

Installation

The quickest way of installing Ruby on Rails with RVM is to run the following commands as a regular user. You will be prompted for your regular...

If you don't want to do everything manually, you can use the railsready script, which will install for you:

An updated system (Linux only) Ruby 1.9.3 latest patch level (installed to /usr/local/bin/ruby) or RVM running 1.9.3 latest patch level Imagemagick libs needed to run Rails (sqlite, mysql, etc) Bundler, Passenger, and Rails gems Git

Just enter the following:

wget --no-check-certificate https://raw.github.com/joshfng/railsready/master/railsready.sh && bash railsready.sh

… and you're done.

As @slotishtype has mentioned, do yourself a favor and install Ruby over RVM. It manages Ruby versions better, you don't need to sudo anything, and you'll be able to get more recent versions of Ruby.

How to install RVM

You need git for that, so if you don't have it, install it with sudo apt-get install git before. Also, @nixterminus has a blog post on that subject, written for Ubuntu 11.04. It features some other dependencies that you might need to...

This is a post on installing Ruby on a Mac. This should work on recent MacOS versions - El Capitan, Sierra, and High Sierra. First of all, Ruby is already pre-installed on your Mac. However, the pre-installed version is a few versions behind so we'll look into the other ways to install Ruby.

Using a package management system makes your life easier when installing any software. On a Mac, you can use Homebrew to install newer versions of Ruby. You can also use it to install a tool that will install Ruby. More on this below.

To install Homebrew, run

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

If you don't like to run a script from a remote site, you can run this instead

cd /usr/local mkdir homebrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew

Most Homebrew packages require a compiler. You can install the Command Line Tools from the command line.

Questions:

My current version of ruby is ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.5.0] but I want to update it to the latest patch level using rvm. How can I do this?

Answers:

First of all, update your RVM installation by running rvm get stable.

To make sure you’re running the new RVM version, you’ll then need to run rvm reload (or just open a new terminal).

Once that’s done, you can ask RVM to list the ruby versions available to install by running rvm list known.

In the output you should now see:

# MRI Rubies ... [ruby-]1.9.2[-p320] ...

The square brackets around the patch level indicate that this is currently RVM’s default patch level for ruby 1.9.2.

Finally, to install the new ruby version, just run rvm install 1.9.2 – and wait for it to compile!

Questions:

Answers:

Upgrade ruby interpreter and keep existing gemsets:

$ rvm upgrade 1.9.2-p0 1.9.2 Are you sure you wish to upgrade from...

Well Ruby 2.4 shipped back in December on the 12th and with almost a month of settle time that means that I now feel its go time for Ruby 2.4 and, specifically, using it on side projects. I’ve already heard talk about Ruby 2.4.1 and the first mistake that I made installing it was to try and use that – which isn’t actually available yet.

The easiest way to see this is to travel over to cache.ruby-lang.org and just view them.

Here’s the easy one liner to install with RVM:

You may need to increase your timeout to get it to install:

echo "export rvm_max_time_flag=20" >> ~/.rvmrc

Like most open source projects, RVM is rich and deep. Here are a few useful commands I used along with way of installing this (the command is in bold; the – SOME TEXT gives an explanation):

rvm list rubies – shows you what rubies are on your system rvm list known – shows you the rubies that rvm knows about (caveat - rvm can install more than it knows about; no I don’t understand...

I am having trouble installing Ruby using RVM. I had tried using readline and other suggestions online. None of the solutions worked.

I use Cygwin, Bash and have RVM installed.

You can use several tools to install Ruby. This page describes how to use major package management systems and third-party tools for managing and installing Ruby and how to build Ruby from source.

Choose Your Installation Method

There are several ways to install Ruby:

When you are on a UNIX-like operating system, using your system’s package manager is the easiest way of getting started. However, the packaged Ruby version usually is not the newest one. Installers can be used to install a specific or multiple Ruby versions. There is also an installer for Windows. Managers help you to switch between multiple Ruby installations on your system. And finally, you can also build Ruby from source.

The following overview lists available installation methods for different needs and platforms.

Package Management Systems

If you cannot compile your own Ruby, and you do not want to use a third-party tool, you can use your system’s package manager to install...

Ruby Version (enVironment) Manager (or simply

RVM

) is a tool that manages Ruby application environments and enables switching between them.


RVM has not been packaged for recent Ubuntu versions (it's only available for Ubuntu

12.04

, but it's a very old RVM version) and to install or update it, you must run a script. To make things easier, WebUpd8 reader Rael G.C. has packaged RVM for Ubuntu and uploaded it to a

PPA

, for easy installation and of course, automatic updates.


Here's what the PPA package does:


installs the latest stable RVM; mixed-mode installation is used: usable by all users on the system, with isolated rubies / gemsets in user's $HOME (see more here); all sudoers are automatic added to rvm group automatically; all sudoers get local gemsets enabled;

Rael's packaging is available on GitHub so if you want to report bugs, make suggestions and so on, see

You’ve probably noticed a few articles as of late on SitePoint and its properties discuss Heroku and their offerings; they’re definitely shaking things up in the cloud services arena! In fact, I recently wrote an article myself discussing Heroku’s database-as-a-service offering, Heroku Postgres. But as a PHP developer of close to 10 years now, I stumbled over a frustrating obstacle when I was exploring their Facebook integration offering… I had to install Ruby!

Well, no, it wasn’t quite like that. You see, I didn’t have Ruby installed on my system and so I first tried to install it using my system’s package management utilities. I’m running Ubuntu 11.10, and so I used apt-get. It all seemed to go well, but I encountered problems when trying to use the heroku gem. After researching everything I ended up installing Ruby myself using the wonderful utility, RVM.

I wanted to share the process of installing Ruby on Ubuntu with RVM since I saw several others had experienced...
