&gt; Mix, Erlang&#x27;s package manager (used by Phoenix &#x2F; Elixir)<p>Slight nitpick: Mix is part of Elixir, I&#x27;ve never seen a (non-elixir) erlang project that use it. Don&#x27;t think erlang has an equivalent officially blessed tool, but the most popular one is rebar &#x2F; rebar3.<p>(While I&#x27;m nitpicking: mix and rebar are more build &amp; dependency managers; mix uses hex for package management. I believe rebar3 can also use hex. In ruby terms, mix ~ bundler (among other things); hex ~ rubygems).
