no case clause matching

I have tried to use the project exvcr but I'm having this problem:

  1) test post events (Keenex.Events.Test)
     test/keenex/events_test.exs:12
     ** (CaseClauseError) no case clause matching: {:error, {:undef, [{:cover, :is_compiled, [:ibrowse], []}, {:meck_proc, :get_cover_state, 1, [file: 'src/meck_proc.erl', line: 392]}, {:meck_proc, :backup_original, 3, [file: 'src/meck_proc.erl', line: 347]}, {:meck_proc, :init, 1, [file: 'src/meck_proc.erl', line: 202]}, {:gen_server, :init_it, 6, [file: 'gen_server.erl', line: 328]}, {:proc_lib, :init_p_do_apply, 3, [file: 'proc_lib.erl', line: 239]}]}}
     stacktrace:

In the project issue, you can have more detailed information such as environment.

It looks like you don't have cover on your path. The cover module is part of the tools application, which I just noticed that Meck is not depending on. Did you run this inside a release you created?

On Debian-based distros, installing the erlang-tools package fixes this. You can also install esl-erlang to get the entire Erlang suite if disk space (or Docker image size...) isn't a concern.

thanks @cwc. I had fixed this problem and I even comment on the solution in issue https://github.com/parroty/exvcr/issues/24#issuecomment-125785876. Sorry for not commenting and closed it.
