I'm sorry but I'm new to Elixir. while building phoenix application, mix deps.get failed with an error.
% mix deps.get
Could not find Hex, which is needed to build dependency :phoenix
Shall I install Hex? [Yn] y

erlang and elixir has been installed via kerl and asdf. and my installation log is here http://otiai10.hatenablog.com/entry/2016/02/03/154953
envirionment
What is happening and what should I do?
As @biletskyy answered, it was missing of SSL on Erlang installed via kerl, unlike via brew.
If you want to build Erlang with ssl via kerl, you should pass KERL_CONFIGURE_OPTIONS like below
KERL_CONFIGURE_OPTIONS="--with-ssl=/usr/local/opt/openssl" kerl build 18.0 18.0-foo
Then install Elixir via asdf. The mix command would work well.
Thanks to @biletskyy
