mix test fails

[acrogenesis]

Running mix test gives:

** (Mix) Could not compile dependency :erlzmq, "make" command failed. You can recompile this dependency with "mix deps.compile erlzmq", update it with "mix deps.update erlzmq" or clean it with "mix deps.clean erlzmq"

Running mix deps.compile erlzmq gives the same error.
Running mix deps.update erlzmq gives:

But doesn't fix mix test
And mix deps.clean erlzmq gives: warning: the dependency erlzmq is not present in the build directory

I was able to get this to work by following the erlzmq2 instructions here

@acrogenesis is there still a problem with compiling erlzmq? I was experimenting with chumak but it seems that chumak is not ready yet.

I had a similar problem. Manually installing rebar solved it.

[pprzetacznik]

@acrogenesis could you check if rebar and rebar3 is properly installed on your machine? Just type rebar and rebar3 in your shell.

This is an awesome thing to have by the way - thank you!

I had a similar problem. Following @DallanQ, manually installing rebar solved it.
I am new to Erlang and Elixir, so I'll elaborate a bit. I did
mix local.rebar
and then added ~/.mix to PATH (mix docs):
export PATH=$PATH:~/.mix
And it worked like a charm.
Thanks @pprzetacznik for the good work!
