Question

我想通过amqp从我的elixir phoenix应用程序中使用rabbitMQ。我按照official website上的教程，但仍然在MyApp.User期间，我收到错误：

mix.deps compile

我在mix.exs文件中只添加了：amqp和{：amqp，“〜＆gt; 0.1.4”}：

include/amqp_gen_consumer_spec.hrl:30: syntax error before: '/'

** (Mix) Could not compile dependency :amqp_client, "/usr/bin/rebar compile skip_deps=true deps_dir="/home/bmarkons/soc2016-marko/telegram/_build/dev/lib"" command failed. You can recompile this dependency with "mix deps.compile amqp_client", update it with "mix deps.update amqp_client" or clean it with "mix deps.clean amqp_client"

我需要做些什么更改才能使我的elixir应用程序与RabbitMQ一起使用？

谢谢

这是:amqp项目中报告的问题（https://github.com/pma/amqp/issues/28）它无法使用Erlang 19进行编译。问题在于:amqp_client。存储库中的最后一个版本是固定的，但它不作为十六进制包存在。

更新2016-08-16：

如果您想在项目中使用AMQP和Erlang 19，只需添加当前:amqp_client依赖关系以覆盖AMQP附带的依赖关系：

def deps do
  [{:amqp_client, git: "https://github.com/jbrisbin/amqp_client.git", override: true},
   {:amqp, "~> 0.1.4"}]
end

对于这个具体的例子，你应该有类似的东西：

defp deps do
  [{:phoenix, "~> 1.2.0"},
   {:phoenix_pubsub, "~> 1.0"},
   {:phoenix_ecto, "~> 3.0"},
   {:postgrex, ">= 0.0.0"},
   {:phoenix_html, "~> 2.6"},
   {:phoenix_live_reload, "~> 1.0", only: :dev},
   {:gettext, "~> 0.11"},
   {:cowboy, "~> 1.0"},
   {:amqp_client, git: "https://github.com/jbrisbin/amqp_client.git", override: true},
   {:amqp, "~> 0.1.4"]
end

重要提示：如果混合文件的混合文件已经覆盖了依赖项，则应覆盖使用:amqp_client事件的项目中的AMQP依赖项。

我希望这会有所帮助。

我必须按如下方式定义依赖关系（分支信息）以使其运行：

defp deps do
[
  {:amqp_client, git: "https://github.com/dsrosario/amqp_client.git", branch: "erlang_otp_19", override: true},
  {:amqp, "~> 0.1.4"}
]
