如何設置Elixir項目通過amqp使用RabbitMQ？

Question

我想通過amqp從elixir phoenix應用程序中使用rabbitMQ。我也跟着教程official website但仍然在mix.deps compile，我得到一個錯誤：

include/amqp_gen_consumer_spec.hrl:30: syntax error before: '/' 
include/amqp_gen_consumer_spec.hrl:31: 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" 

Terminal screenshot

我只加：AMQP和{：AMQP， 「〜> 0.1.4」}，在mix.exs文件：

def application do 
    [mod: {App, []}, 
    applications: [:phoenix, :phoenix_pubsub, :phoenix_html, :cowboy, :logger, :gettext, 
        :phoenix_ecto, :postgrex, :amqp]] 
end 

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, "~> 0.1.4"}] 
end 

我需要做些什麼改變，讓我的elixir應用程序與rabbitMQ一起工作？

謝謝

它在:amqp項目（https://github.com/pma/amqp/issues/28）未使用Erlang 19編寫問題在於:amqp_client報告的問題。存儲庫中的最後一個版本是固定的，但它不是作爲十六進制包存在的。

更新2016年8月16日：

如果你想使用AMQP使用Erlang 19在你的項目只是添加當前:amqp_client依賴覆蓋附帶AMQP之一：

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

對於這個具體的例子，你應該有這樣的東西：

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 

Important: You should override the :amqp_client dependency in projects that use AMQP event if their mix file is already overriding the dependency.

我希望這會有所幫助。

我不得不定義如下（分支信息），以得到它的運行依賴：

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