Ruby is popular programming language among large number of developers. Rails is 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 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 | gpg2 --import - # curl -sSL https://get.rvm.io | bash -s stable
After installing RVM first we need to set up rvm environment using below command. so that current shell takes new environment settings.
# source /etc/profile.d/rvm.sh
Install Ruby Dependencies
Install all the dependencies for installing Ruby automatically on system. Run below command on terminal.
# rvm requirements
Step 2 – List Available Ruby Versions
Get a list of available versions of Ruby language. You can install any version of your choice or requirements showing in list.
# rvm list known
[ruby-]1.8.6[-p420] [ruby-]1.8.7[-head] # security released on head [ruby-]1.9.1[-p431] [ruby-]1.9.2[-p330] [ruby-]1.9.3[-p551] [ruby-]2.0.0[-p648] [ruby-]2.1[.10] [ruby-]2.2[.7] [ruby-]2.3[.4] [ruby-]2.4[.1] ruby-head
Step 3 – Install Ruby Version
RVM is useful for installain of multiple Ruby versions on single system. Use the following command to install required Ruby on your system. As shown below example will install Ruby 2.4.1 on your system.
# rvm install2.4.1
[Sample Output]
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-2.4.1.tar.bz2
Checking requirements for ubuntu.
Requirements installation successful.

ruby-2.4.1 - #importing gemsetfile /usr/local/rvm/gemsets/default.gems evaluated to empty gem list
ruby-2.4.1 - #generating default wrappers........
Step 4 – Setup Default Ruby Version
Use rvm command to set up default ruby version to be used by applications. You can install multiple versions by running command multiple times with different versions using above command. Now select which version you want to use.
#rvm use 2.4.1 --default Using /usr/local/rvm/gems/ruby-2.4.1
Step 5 – Check Ruby Version
Using following command you can check the current ruby version is used.
#ruby --version ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux]
Step 6 – Install Rails
We can install latest stable release version of Rails by running following command. It will install Rails in global gemset, So that all applications share the same version of Rails.
# gem install rails # rails -v
Or we can get a specific version of Rails by defining –version during installation. Visit here to get available rails versions.
# gem install rails --version=5.1.4
I hope above steps will help you for installing multiple Ruby version using RVM and Rails versions.
Thanks for the tutorial.
It didn’t work with Linux Mint. I think rvm does not recognize Mint as an Ubuntu derivative. It does not find binaries for Mint and the compile fails. I tried various different version numbers and the compilation errors are slightly different but generally some files are not found e.g. ‘strlcat.c’
It’s Work, thanks for this tips !
How to fix bash: /etc/profile.d/rvm.sh: No such file or directory
Just open new terminal window to start anew. I too did not find the file but it was not needed.
Good tutorial!
everything works fine sometime you just need to type “sudo” before camands to get root permissions
thank you Rahul
Not a good tutorial. Nothing was saved even when I ran the commands as root.
In my instance I had to enable the “Run command as a login shell” option for my terminal in Mint.
Edit > Profile Preferences > Title and Command > Run Command as login shell
Everything worked perfectly after that.
You do not need to do that. Instead use command
$> rvm alias create default X.Y.Z
when setting the default ruby. (change X,Y,Z for the correct numbers)
If not sure about the numbers/versions, use
$> rvm list
to see what versions you have installed
This works, but when i turn off the terminal its all gone? Why, i was using terminal in root mode.
same thing happened to me
Hi Joe,
Can you please explain your issue more ?
Hi Rahul
I installed the program as root but when I log on as a normal user it’s not available.
Would I need to reinstall as normal user or is there another way?
Many thanks
you must type:
# source /etc/profile.d/rvm.sh
every time before working with it. I’v added this line to .bashrc file in my home directory on linux mint. Now it is fine and no need to type it every time.
