Installing Ruby using Rbenv #

Rbenv is a lightweight Ruby form the board utility that permits you to effortlessly switch Ruby variants.

We’ll use the ruby-build plugin that extends the core functionality of Rbenv and allow you to install any Ruby version from source.

Start by introducing git and different conditions required to fabricate Ruby from the source:

sudo apt update
sudo apt install git curl libssl-dev libreadline-dev zlib1g-dev         autoconf bison build-essential libyaml-dev         libreadline-dev libncurses5-dev libffi-dev libgdbm-dev

Run the following command to install both rbenv and ruby-build scripts:

curl -sL | bash -

The script will clone both rbenv and ruby-build repositories from GitHub to ~/.rbenv directory.

To start using rbenv, you need to add $HOME/.rbenv/bin to your PATH.

If you are using Bash:

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrcecho 'eval "$(rbenv init -)"' >> ~/.bashrcsource ~/.bashrc

If you are using Zsh:

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.zshrcecho 'eval "$(rbenv init -)"' >> ~/.zshrcsource ~/.zshrc

Run the rbenv -v command to ensure that installation was successful:

rbenv -v
rbenv 1.1.2-26-gc6324ff

To get a list of all Ruby versions that can be installed with rbenv enter:

rbenv install -l

For example, to install Ruby version 2.7.0 and set it as default version, you would type:

rbenv install 2.7.0rbenv global 2.7.0

Verify that Ruby was properly installed:

ruby -v
ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux]

Install Ruby using RVM #

RVM (Ruby Version Manager) is an order line device that permits you to introduce, oversee, and work with various Ruby situations.

Install the dependencies required to build Ruby from source:

sudo apt update
sudo apt install curl g++ gcc autoconf automake bison libc6-dev         libffi-dev libgdbm-dev libncurses5-dev libsqlite3-dev libtool         libyaml-dev make pkg-config sqlite3 zlib1g-dev libgmp-dev         libreadline-dev libssl-dev

Run the following commands to add the GPG key and install RVM:

gpg --keyserver hkp:// --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDBcurl -sSL | bash -s stable

To start using RVM, enter:

source ~/.rvm/scripts/rvm

To get a list of all known Ruby versions type:

rvm list known

Install the latest stable version of Ruby with RVM and set it as the default version:

rvm install rubyrvm --default use ruby

Verify that Ruby was properly installed by printing the version number:

ruby -v
ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-linux]

If you want to install a specific version of Ruby, enter the commands below. Replace x.x.x with the Ruby version you want to install:

rvm install ruby-x.x.xrvm --default use ruby-x.x.x

For more information about how to manage your Ruby installations with RVM check their Documentation page.

Conclusion #

We have given you three unique approaches to introduce Ruby on your Debian 10 server. The strategy you pick relies upon your prerequisites and inclinations. Despite the fact that introducing the bundled form from the Debian storehouse is simpler, the Rbenv and RVM techniques give you greater adaptability for including and expelling diverse Ruby forms on a for every client premise.
