could not compile dependency :phx_new, "mix compile" failed. You can recompile this dependency with "mix deps.compile phx_new", update it with "mix deps.update phx_new" or clean it with "mix deps.clean phx_new"

I already tried with mix deps.compile phx_new", mix deps.update phx_new and mix deps.clean phx_new

mix archive.uninstall phx_new and you should be good to go!

[josevalim]

Alternatively phx_gen_auth can add this to its mix.exs file:

for path <- :code.get_path,
    Regex.match?(~r/phx_new\-\d+\.\d+\.\d\/ebin$/, List.to_string(path)) do
  Code.delete_path(path)
end

But this problem will also be solved once we merge it into Phoenix. :)

Another option is to use MIX_ENV=prod mix compile
