I haven't personally used the cassandra_ecto library, but this error usually means that a dependency is missing from your application. Do you have the cqerl library listed in your deps function?

def deps do
  [
    {:cqerl, github: "matehat/cqerl", tag: "v1.0.4"},
    ...
  ]
end

If so, have you also added it to your list applications that should be started?

def application do
  [applications: [:cqerl, ...]]
end

  • Thanks, I have used 1.0.2 version, now i changed the version to 1.0.4. Now that issue was fixed, but created new issue as ` Could not start application cas: Cas.start(:normal, []) ' – petspanda D Apr 12 '17 at 10:03
  • I am guessing it's a similar issue, try adding `:cas` to your applications list as you did with `:cqerl` – Stuart Apr 12 '17 at 10:55
