编译 Elixir NIF 时出现错误 `unknown application: :nif_bartender`

Question

我正在为 Elixir 绑定到 rustrict ，但是当为 FreeBSD 编译它时（Elixir 1.14.4，OTP 25，我使用的是 serv00 中的服务器），它给了我这个错误：

[LOGIN@s1]:<~/domains/LOGIN.serv00.net/backend>$ linker=gcc mix compile
==> nif_bartender
Compiling 1 file (.ex)

== Compilation error in file lib/bartender.ex ==
** (ArgumentError) unknown application: :nif_bartender
    (elixir 1.14.4) lib/application.ex:954: Application.app_dir/1
    (elixir 1.14.4) lib/application.ex:981: Application.app_dir/2

could not compile dependency :bartender, "mix compile" failed. Errors may have been logged above. You can recompile this dependency with "mix deps.compile bartender", update it with "mix deps.update bartender" or clean it with "mix deps.clean bartender"

这是来自 hex.pm 的 0.1.2 版本，我似乎找不到它是什么。在克隆实际存储库时，我可以完美地运行

mix test

，我什至可以制作一个仅运行审查功能的测试应用程序。它只发生在这个应用程序中。

关闭。在 Bartender 库的 mix.exs 中使用 Mixfile 而不是最新的 MixProject。更新了它和 lib/bartender.ex 以使用

use Rustler, otp_app: :bartender

而不是

use Rustler, otp_app: :nif_bartender, crate: :bartender

，现在可以使用了。
