Install asdf

Check this link for more information

Ruby and Elixir are my drugs of choice.

git clone https://github.com/asdf-vm/asdf.git ~/.asdf

# reload terminal

asdf plugin-add ruby https://github.com/asdf-vm/asdf-ruby.git && \
asdf plugin-add erlang https://github.com/asdf-vm/asdf-erlang.git && \
asdf plugin-add elixir https://github.com/asdf-vm/asdf-elixir.git

echo -e '\n. $HOME/.asdf/asdf.sh' >> ~/.zshrc
echo -e '\n. $HOME/.asdf/completions/asdf.bash' >> ~/.zshrc

# reload terminal again!

Now you can install a language version using

# asdf install language version
asdf install ruby 2.6.3

Set your local language for a project (and create your .tool-versions file in the root)

# asdf install language version
asdf local ruby 2.6.3

and your global version

# asdf install language version
asdf install ruby 2.6.3

don’t forget to add your .default-gems file in your home directory! It will install the specified gems every time you install a new ruby version.

touch ~/.default-gems

and put in your essentials!
