Could not compile dependency :jiffy

Question

I'm trying to run a mix server:

...
Compiling c_src/decoder.c
sh: 1: exec: cc: not found
===> Hook for compile failed!

** (Mix) Could not compile dependency :jiffy, "/home/user/.mix/rebar3 bare compile --paths "/home/user/app_build/_build/prod/lib/*/ebin"" command failed. You can recompile this dependency with "mix deps.compile jiffy", update it with "mix deps.update jiffy" or clean it with "mix deps.clean jiffy"
...

Is there any solution for this case?

$ mix local.rebar
$ rm -rf deps
$ rm -rf _build
$ mix deps.get

Not helping :-(

It sounds like you do not have a C compiler installed. Try $ apt-get install build-essential to install one.
