And ond path

/Users/.../_build/dev/lib/fs/ebin/fs_app.beam

mandatory chunk of type 'Atom' not found

Try to switch Erlang releases, this is due wrong byte-code for actual Virtual Machine.

Therefore you may close this issue, because we do not provide BEAM files in any installation.

Ok, I found the problem. I was needed to delete deps dir(it was compiled for another version of erlang). Thank you for a quick answer!
