I couldn't find a solid set of instructions on how to do this so I decided to write it up quick. I did find a lot of tutorials for Ubuntu, but they seemed to encounter errors on elementary OS.
This is basically a lot of copy paste. I've gone through all the steps on elementary and it works like a charm.
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
- Open your .bashrc with nano
- make sure you type or past the following lines into the bottom of your .bashrc
esac # rbenv export PATH="$HOME/.rbenv/bin:$PATH" eval "$(rbenv init -)" export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"
- ctrl-o to save
- ctrl-x to quit
rbenv install 2.7.1
rbenv gloabal 2.7.1
From here you should be able to install Rails or any other gems you wish.
Like I said, quick and dirty. I hope this helps people so they don't have to dig around as much for instruction.
