Question

我成功地使用了对于简单的Hello World重新绑定和OTP“兼容”应用程序的rabbitmq-erlang-client的rebar友好包，并且在开发环境中工作正常。我能够启动一个erl控制台并执行我的application:start(helloworld).并连接到代理，打开一个频道并与队列进行通信。

然而，我继续做rebar generate并且它很好地构建了发布，但是当我尝试从自包含的发行包中启动时，事情突然爆发。

我知道螺纹钢的发布是一项晦涩难懂的艺术，但我想知道在使用rabbitmq-erlang-client进行应用程序部署时我的选择是什么。

下面你会看到崩溃时控制台的输出：

Answer 1

尝试将{mod_cond, derived}更改为{mod_cond, all}。这意味着reltool不会试图巧妙地从所包含的应用程序中获取哪些模块。我怀疑你的问题是reltool不认为amqp_connection_sup是必要的;您可以通过检查lib/amqp_client-0.8/ebin中是否存在来确认。

@legoscia给出的答案有效。这是示例，reltool.config

rabbitmq-erlang-client，使用rebar friendly pkg，在dev env上工作，在rebar发布时失败
