By default Rebar3 wants to manage it's own dependencies. In the
normal non-Nix, this is perfectly acceptable. In the Nix world it
is not. To support this we have created two versions of rebar3,
<literal>rebar3</literal> and <literal>rebar3-open</literal>. The
<literal>rebar3</literal> version has been patched to remove the
ability to download anything from it. If you are not running it a
nix-shell or a nix-build then its probably not going to work for
you. <literal>rebar3-open</literal> is the normal, un-modified
rebar3. It should work exactly as would any other version of
rebar3. Any Erlang package should rely on
<literal>rebar3</literal> and thats really what you should be
using too.
