Sql server 针对不同目标发布的ERT包括

我想知道是否有人能帮忙

我试图从Elixir应用程序中连接到MS SQL Server，但收到错误

：odbc.start/0未定义（模块：odbc不可用）

在我的Mac上，我安装了带有ODBC支持的Erlang，一切都很好，但是当我在Ubuntu服务器（我为其安装了Erlang ODBC，并且在构建的地方）上部署Divertery和edeliver时，它失败了。我还尝试不包括ERT，并在我的机器上复制Erlang的lib后在本地构建它，但都没有效果

这是edeliver配置文件的一个片段：

BUILD_HOST="search-dev"
BUILD_USER="ubuntu"
BUILD_AT="/home/ubuntu/app_build"

STAGING_HOSTS="search-dev search-demo"
STAGING_USER="ubuntu"
TEST_AT="/home/ubuntu/app_release"
...

更新 mix.exs

defmodule SearchService.Mixfile do
  use Mix.Project

  def project do
    [
      app: :search_service,
      version: "0.9.0",
      elixir: "~> 1.7",
      elixirc_paths: elixirc_paths(Mix.env()),
      compilers: [:phoenix, :gettext] ++ Mix.compilers(),
      start_permanent: Mix.env() == :prod,
      aliases: aliases(),
      deps: deps()
    ]
  end

  def application do
    [
      mod: {SearchService.Application, []},
      extra_applications: [
        :logger,

        :httpoison
      ]
    ]
  end

    ]
  end

  defp aliases do
    [
      "ecto.setup": ["ecto.create", "ecto.migrate", "run priv/repo/seeds.exs"],
      "ecto.reset": ["ecto.drop", "ecto.setup"],
      test: ["ecto.create --quiet -r SearchService.Repo", "ecto.migrate -r SearchService.Repo", "test"]
    ]
  end

  def blue_bird_info do
    [
      host: "https://search_service.com",
      title: " Search API",
      description: """
        API requires authorization. All requests must have valid authorization header containing token like:

        `Authorization: Bearer eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9...`
      """
    ]
  end
end

我希望：odbc模块可用，从而允许我连接到SQLServer，而当我在服务器上运行远程控制台时，我得到了

Interactive Elixir (1.9.1) - press Ctrl+C to exit (type h() ENTER for help)
iex(search_service@127.0.0.1)1> SearchService.WorkOrderSyncOut.createWO('c765bc7f-6308-42b3-b5da-647830d5cceb')
** (UndefinedFunctionError) function :odbc.start/0 is undefined (module :odbc is not available)
    :odbc.start()
    (search_service) lib/search_service/sync/odbc.ex:5: SearchService.ODBC.start_link/2

提前感谢您的指点

要将应用程序包括到发行版中，就应该明确地这样做

def application do
  [
      mod: {SearchService.Application, []},
      included_applications: [:odbc], # ⇐ THIS
      extra_applications: [:logger, ...]
  ]
end

该版本不同于本地运行，因为在本地您仍然可以编译包，并且

mix

runner可以看到相应的

.beam

产品构建已打包，并且该包仅包括那些明确指定的应用程序/库

---

旁注：尝试从发行版代码中调用

Mix.env（）

或类似程序失败的方式与此完全相同，因为默认情况下，

Mix

应用程序也不包括在发行版中。

请共享您的

Mix.exs

和完整的堆栈跟踪。尝试添加

包含的应用程序：[:odbc]

进入

def应用程序do

。如果没有帮助，请将其放入

extra\u应用程序

列表中。默认情况下，该版本不会包括您机器上的所有内容。@AlekseiMatiushkin非常感谢您，确实

包含了应用程序：[:odbc]

解决了这个问题。如果你想回答这个问题，我会同意的：-）
