3. Installing rbenv and Ruby on Linux
Last Updated: 26 Nov 2018, Credit to: The Odin Project
Update:
sudo apt-get update
sudo apt-get upgrade
Install misc packages:
sudo apt-get install curl git nodejs gcc make libssl-dev libreadline-dev zlib1g-dev libsqlite3-dev
Install rbenv: (last command closes your terminal deliberately)
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exit
Get ruby plugin:
mkdir -p "$(rbenv root)"/plugins
git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build
Install ruby: (2.5.3 was the current version as of this writing)
rbenv install 2.5.3 --verbose
Set Ruby version and verify it is installed:
rbenv global 2.5.3
ruby -v
Done!
