Installing Elixir

As I said previously, I want to make my posts very short and concise and this is not going to be the exception.

If you're using Windows, I highly recommend install WSL so you will have the best of Linux and Windows at the same time.

Having said so, the commands I show here will work for MacOS, Linux and Windows(WSL).

I highly recommend installing Elixir with asdf since if you are lucky enough to work with Elixir in a professional project, you might find yourself changing the version several times, so for me, this is the best option for doing it so. So this guide will show you how to do it with asdf

The first thing you're going to do is install Homebrew (I know, you can install it directly as the official web page says, but I think it's way easier using Homebrew instead)

So, step 1. Install Homebrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Remember to add brew to your .zshrc .bashrc... file (or the one you're using).

export BREW_HOME="/home/linuxbrew/.linuxbrew/bin"
export PATH="$PATH:$BREW_HOME"

Step 2, install asdf:

brew install asdf

Step 3, add Erlang and Elixir plugin with asdf:

asdf plugin-add erlang https://github.com/asdf-vm/asdf-erlang.git

asdf plugin-add elixir https://github.com/asdf-vm/asdf-elixir.git

Step 4, install the latest Erlang and Elixir versions (or the one you want)

asdf install erlang 25.3

asdf install elixir 1.14.4

And that's all, you can change locally or globally your Elixir version with a single command.

Remember to add to your .bashrc (or the one you're using) the shims from asdf

export PATH=~/.asdf/shims:$PATH

You can type iex at your terminal to make sure that everything went well:

iex
Erlang/OTP 24 [erts-12.0.4] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [jit]

Interactive Elixir (1.13.1) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)>

Note: as you might see I have Elixir 1.13.1 and Erlang 24.

Edit 1:
I added the .bashrc to the files to add the Homebrew variables

I added the shims path.
