asdf erlang installation for OTP 24

• install asdf package manager via homebrew

$ brew install asdf

• add erlang plugin

$ asdf plugin add erlang

• install autoconf

$ brew install autoconf

• install erlang

Because of privileges issues on my laptop, I intended to use sudo command.

$ sudo asdf install erlang latest

On the other hand, you can also use a simple asdf command if you are confident that you have the right privileges in your laptop.

$ asdf install erlang latest

• run erl -v command and see to it that you have seen this
