Problems when instantiating Faker in iex, I followed the documentation guide but it didn't help me much, can someone help me, I'm using Phoenix Framework

Faker.Address.zip_code()
** (UndefinedFunctionError) function Faker.Address.zip_code/0 is undefined (module Faker.Address is not available)

`mix.exs

defmodule Proje.MixProject do
use Mix.Project

def project do
[
app: :proje,
version: "0.1.0",
elixir: "~> 1.7",
elixirc_paths: elixirc_paths(Mix.env()),
compilers: [:phoenix, :gettext] ++ Mix.compilers(),
start_permanent: Mix.env() == :prod,
aliases: aliases(),
deps: deps()
]
end

Configuration for the OTP application.

Type mix help compile.app for more information.

def application do
[
mod: {Proje.Application, []},
extra_applications: [:logger, :runtime_tools]
]
end

Specifies which paths to compile per environment.

defp elixirc_paths(:test), do: ["lib", "test/support"]
defp elixirc_paths(_), do: ["lib"]

Specifies your project dependencies.

Type mix help deps for examples and options.

defp deps do
[
{:phoenix, "> 1.5.4"},
{:phoenix_ecto, "> 4.1"},
{:ecto_sql, "> 3.4"},
{:myxql, ">= 0.0.0"},
{:phoenix_html, "> 2.11"},
{:phoenix_live_reload, "> 1.2", only: :dev},
{:phoenix_live_dashboard, "> 0.2"},
{:telemetry_metrics, "> 0.4"},
{:telemetry_poller, "> 0.4"},
{:gettext, "> 0.11"},
{:jason, "> 1.0"},
{:plug_cowboy, "> 2.0"},
{:faker, "> 0.15", only: :test}
]
end

Aliases are shortcuts or tasks specific to the current project.

For example, to install project dependencies and perform other setup tasks, run:

$ mix setup

See the documentation for Mix for more info on aliases.

defp aliases do
[
setup: ["deps.get", "ecto.setup", "cmd npm install --prefix assets"],
"ecto.setup": ["ecto.create", "ecto.migrate", "run priv/repo/seeds.exs"],
"ecto.reset": ["ecto.drop", "ecto.setup"],
test: ["ecto.create --quiet", "ecto.migrate --quiet", "test"]
]
end
end

test_helper.exs

ExUnit.start()
Faker.start()
Ecto.Adapters.SQL.Sandbox.mode(Proje.Repo, :manual)

Where are you using Faker.Address.zip_code/0? In a test? In the REPL?
