Not getting proper Code completion and strange behaviour in Ubuntu

The linter works but the linter shows this error. I am working on test project on phoenix called HelloPhoenix. For the code use HelloPhoenix.Web, :view

And this is the error I get Error: module HelloPhoenix.Web is not loaded and could not be found. But mix does not have any complaints and the project runs on server.

Code completion does not work as shown. Like the Enum module is not showing on auto completion but def,defmacro,receive are working.

I tried to change the user settings but it made no effect

"env":
    {
        "PATH": "/usr/local/lib/elixir/bin"
    }

Using Ubuntu 14.04LTS Sublime Text 3

Any update on this issue?
