凤凰部署与 EXRM 牛仔服务器回答 500

Question

我的新项目（我只在默认 mix new proj 的主页上添加了“hello world”）在 dev 中运行良好

我根据 phoenix site 部分将其配置为 prod，然后使用此命令

 MIX_ENV=prod iex -S mix phoenix.server

效果很好

之后我通过混合发布创建了发布 - 在此过程中一切都很好

之后我尝试启动此版本，它启动了，但没有工作：

什么？如何？ （我已阅读 phoenixframework.org 上的“部署”部分）

$> mix -v
Mix 1.2.4



$> elixir -v
Erlang/OTP 18 [erts-7.3] [source] [64-bit] [smp:2:2] [async-threads:10] [hipe] [kernel-poll:false]

Elixir 1.2.4

Tnx

好的，我找到了我的麻烦的原因

在主 OTP 中已经存在牛仔 cowlib 和牧场（在 /usr/lib/erlang/lib 目录中） 删除它们后 - 一切正常！
