How to Install Ruby on Fedora 33/32/31/30 with RVM. Ruby is a dynamic, object-oriented programming language. We are using RVM, which stands for Ruby Version Manager, which makes easier to install Ruby on Linux platform. RVM is also helpful for managing multiple version of Ruby without conflicting, and we can switch the system to any version of Ruby using a single command.
This tutorial will help you to install Ruby stable release on your Fedora systems using RVM.
Step 1 – Prerequisites
First of all, we need to install all required packages for ruby installation on our system using the following command. Login to your Fedora system and open terminal.
sudo dnf install gcc-c++ patch readline readline-devel zlib zlib-devel \
libyaml-devel libffi-devel openssl-devel make \
bzip2 autoconf automake libtool bison sqlite-devel
Step 2 – Install RVM
Then, 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 | sudo gpg2 --import -curl -sSL https://rvm.io/pkuczynski.asc | sudo gpg2 --import -curl -L get.rvm.io | sudo bash -s stable
Also, run below command to load RVM environment.
source /etc/profile.d/rvm.shrvm reload
Step 3 – Verify Dependencies
Now use the following command to verify all dependencies are properly installed.
rvm requirements run
Checking requirements for fedora.
Requirements installation successful.
Step 4 – Install Ruby on Fedora
Now, your system is ready for the Ruby installation. You can find the available Ruby version for installation using below command.
rvm list known
Then install the required Ruby version on your system. Here, I am installing Ruby 2.6 on my Fedora 30 system. You can simply replace the version to below command of your choice and install.
sudo rvm install 2.7
Step 5 – Setup Default Ruby Version
First of all, check currently installed ruby versions on your system.
rvm list
ruby-2.4.4 [ x86_64 ]
* ruby-2.5.1 [ x86_64 ]
=> ruby-2.7.0 [ x86_64 ]
# => - current
# =* - current && default
# * - default
After that use rvm command to set up the default ruby version to be used by applications.
sudo rvm use 2.7 --default
Using /usr/local/rvm/gems/ruby-2.7.0
Step 6 – Check Current Ruby Version.
Using following command you can check the current ruby version is used.
ruby --version
ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux]
Congratulation’s, Finally you have successfully installed Ruby on your system. Read our next article to integrate Ruby with Apache web server with easy steps.

Doing “sudo -i” at the begginig is a terrible idea. In worst case scenario it may render using some of the tools absolutly impossible (it will be impossible to use “gem install” for example), and the mess it creates is very difficult to fix.
So this will install rvm and ruby on your system all right. But it will be useless for most of the part, and it will create a major mess on your system.
Don’t use sudo -i, instead use sudo where you actually need it.
Thanks Sebastian, You are write, tutorial has been updated accordingly
Fedora 33
$ sudo rvm install 2.7
sudo: rvm: command not found
is it gpg2 instead of gpg3?
Thanks Bumbaa, Article has been updated.
Thanks dear for help really helpful .
Good tutorial. Just a quick correction; you have “rvm install 2.3.3,” but I’m sure you meant “rvm install 2.3.5.” Keep up the good work!
