By Complete I don’t mean you are a complete beginner to programming. You will need to know how to type these commands in your terminal or ask for help. I mean that the guide is complete. This guide should get everything installed for you to start following any Elixir tutorial, including Kiex which will enable you to switch between Elixir versions for different guides.

Install Dependencies, this is the only part that would be different on OSX.

sudo apt update
sudo apt purge erlang
sudo apt autoremove -y
sudo apt install bash curl erlang git make openssl vim -y

Check your Erlang Version

erl -eval 'erlang:display(erlang:system_info(otp_release)), halt().'  -noshell
# This should be 20 or higher

Install Kiex

\curl -sSL https://raw.githubusercontent.com/taylor/kiex/master/install | bash -s

Add what is in the quotes to your .rc file or copy/paste the whole command into your terminal which will add the relevant bits to the bottom of your .bashrc

RUN echo '[[ -s "$HOME/.kiex/scripts/kiex" ]] && source "$HOME/.kiex/scripts/kiex"' >> .bashrc
RUN echo 'export PATH="$HOME/.kiex/bin:\$PATH"' >> .bashrc
