Question

我在尝试在生产中部署我的应用程序时遇到错误，编译步骤由于某种原因而失败，具有以下内容

== Compilation error in file lib/my_app_web/endpoint.ex ==
** (UndefinedFunctionError) function 
Phoenix.Endpoint.Supervisor.config/2 is undefined (module 
Phoenix.Endpoint.Supervisor is not available)
Phoenix.Endpoint.Supervisor.config(:my_app, 
MyAppWeb.Endpoint)
lib/my_app_web/endpoint.ex:2: (module)
(stdlib) erl_eval.erl:670: :erl_eval.do_apply/6

我可以在本地（macOS）构建它，但不能在服务器上构建（ubuntu）

MACOS

➜ elixir -v
Erlang/OTP 20 [erts-9.3] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]

Elixir 1.6.4 (compiled with OTP 20)

ubuntu的

elixir -v
Erlang/OTP 20 [erts-9.1] [source] [64-bit] [smp:2:2] [ds:2:2:10] [async-threads:10] [hipe] [kernel-poll:false]

Elixir 1.6.5 (compiled with OTP 19)

我只注意到19岁而不是20岁的elixir和OTP的小补丁，但自从它在服务器上编译后，我看不出这是怎么回事

这是有问题的文件
