Rabbitmq Client from erlang shell throwing error - erlang

Question

I am trying connect to rabbitmq using amqp_client library. I followed the steps provided here.
My rabbitmq version is RabbitMQ 3.5.7, Erlang 18.3. So I downloaded respective files from https://www.rabbitmq.com/releases/rabbitmq-erlang-client/v3.5.7/. and unzipped to "/usr/lib/erlang/lib/" path. then in erlang shell i started like below
application:start(xmerl).
application:start(amqp_client).
application:start(rabbit_common).
rr("/usr/lib/erlang/lib/amqp_client-3.5.7/include/amqp_client.hrl").
#amqp_params_network{}.
{ok, Connection} = amqp_connection:start(#amqp_params_network{port=5672}).
In this step I got Some crash report

I am not getting why I am getting this error?

Answer 1

[{undef,[{rabbit_misc means that it can't find the function.
you should try to execute the program using erl -pa /your_path_beam and put there all the .beam files.
Another way is to use rebar3 where you can easily create and app and the add amqp_client dependency ( from https://hex.pm/).
It is very similar to java maven
