Can't start comeonin with Bcrypt

I am adding user Authentication to my webapp and for some reason I am having issues and really don’t know how to solve it (I don’t know if it’s an error on my side or a bug).

(Just as an heads up, I am using windows and I have nmake installed)

I try to add comeonin and Bcrypt like so:

     {:comeonin, "~> 5.0"},
     {:bcrypt_elixir, "~> 2.0"}

Then I do mix deps,get and mix deps.compile bcrypt_elixir, which works completely well and I don’t get any errors.

When I do mix phoenix.server I get the following warning (I am using hash_pwd_salt/1):

warning: function Comeonin.Bcrypt.hash_pwd_salt/1 is undefined or private. Did you mean one of:

      * hashpwsalt/1
      * hashpwsalt/2

If I try using hashpwsalt/1 I get:

** (exit) an exception was raised:
    ** (ArgumentError) Comeonin.Bcrypt.hashpwsalt has been removed.
Add {:bcrypt_elixir, "~> 2.0"} to the deps in your mix.exs file,
and use Bcrypt.hash_pwd_salt instead.

        (cowboy) c:/Users/Zastrix/Documents/Phoenix/dealmailer-phoenix/deps/cowboy/src/cowboy_protocol.erl:442: :cowboy_protocol.execute/4

Then I try to downgrade my versions:

     {:comeonin, "~> 4.0"},
     {:bcrypt_elixir, "~> 1.0"}

And I get the dependencies and compile, everything is okay. I don’t get warnings in console when I start the app but when I do actually run it… I get this again (I am using hashpwsalt/1 here)

** (exit) an exception was raised:
    ** (ArgumentError) Comeonin.Bcrypt.hashpwsalt has been removed.
