Installing Erlang

To install the Phoenix we need to install the Erlang. Erlang can be installed by running the following commands in our terminal:

apt-get update 
apt-get install -y wget 
rm -rf /var/lib/apt/lists/* 
wget https://packages.erlang-solutions.com/erlang-solutions_2.0_all.deb &&\
    dpkg -i erlang-solutions_2.0_all.deb || true
ARG DEBIAN_FRONTEND=noninteractive

Mac

brew update
brew install erlang

Erlang will be installed on our system.

Installing Elixir

We also need to install the Elixir to install Phoenix. Elixir can be installed by the following commands.

apt-get update &&\
apt-get install -y erlang &&\
apt-get install elixir

Elixir will be installed on our system.

Installing Phoenix

Before installing Phoenix, first, install local.hex as it is required to install Phoenix.

mix local.hex --force

To check the version of Elixir and Erlang, run the following:

elixir -v

After verifying the versions, install Phoenix by running the following command:

mix archive.install hex phx_new 1.5.9 --force

Phoenix will now be installed on our system.

Verify Phoenix version.

mix phx.new --version
