无法编译依赖项：salty，“混合编译”失败

Question

我正在使用 mix compile 编译我的应用程序，并且依赖项 salty 发生错误。

我已经添加了依赖salty 和libsodium。 但仍然没有解决错误。

这是我的 mix.exs 文件，其中包含所有依赖项。

defp deps do
    [
      {:poison, "~> 3.0", override: true},
      {:syndicate, in_umbrella: true},
      {:xarango, "~> 0.7.0"},
      {:ecto, "~> 3.1"},
      {:phoenix, "~> 1.4.0"},
      {:gettext, "~> 0.11"},
      {:cowboy, "~> 2.6"},
      {:joken, "~> 2.0"},
      {:ecto_sql, "~> 3.0"},
      {:jason, "~> 1.0"},
      {:postgrex, ">= 0.0.0"},
      {:sage, "~> 0.4.0"},
      {:salty, "~> 0.1.3", hex: :libsalty},
      {:libsodium, "~> 0.0.10"}
    ]
  end

它应该可以完美编译，但它会抛出一个错误

could not compile dependency :salty, "mix compile" failed. You can recompile this dependency with "mix deps.compile salty", update it with "mix deps.update salty" or clean it with "mix deps.clean salty"
** (Mix) Could not compile with "make" (exit status: 2).
You need to have gcc and make installed. If you are using
Ubuntu or any other Debian-based system, install the packages
"build-essential". Also install "erlang-dev" package if not
included in your Erlang/OTP version. If you're on Fedora, run
"dnf group install 'Development Tools'".

正如 cmets 中提到的，安装 libsodium 1.0.12+ 可以解决问题。
