Please fix the error in the installation instructions for node

for more comfortable setup, add this code in mix.exs

  # Aliases are shortcuts or tasks specific to the current project.
  # For example, to create, migrate and run the seeds file at once:
  #
  #     $ mix ecto.setup
  #
  # See the documentation for `Mix` for more info on aliases.
  defp aliases do
    ["ecto.setup": ["ecto.create", "ecto.migrate"],
     "ecto.reset": ["ecto.drop", "ecto.setup"],
     "test": ["ecto.create --quiet", "ecto.migrate", "test"]]
  end
