Question

我的功能很简单：

do_stuff(_Whatever) ->
  jiffy:decode(<<"{\"foo\": \"bar\"}">>).

正如您所看到的，它取决于库jiffy。所以我在rebar.config中添加了它：

{deps, [
  {cowboy, {git, "https://github.com/ninenines/cowboy", {tag, "2.0.0-pre.1"}}},
  {jiffy, {git, "https://github.com/davisp/jiffy", {tag, "0.14.8"}}}
]}.
{relx, [{release, { myapp, "0.1.0" },
     [vizcerl,
      sasl
      ]},

    %{sys_config, "./config/sys.config"},
    %{vm_args, "./config/vm.args"},

    {dev_mode, true},
    {include_erts, false},

    {extended_start_script, true}]
}.

但是，当我运行rebar3 run并且程序得到这样做时，我得到的错误是该函数未定义。

编辑：我运行rebar3 tree来检查dep是否被识别，结果是：

└─ myapp─0.1.0 (project app)
   ├─ cowboy─2.0.0-pre.1 (git repo)
   │  ├─ cowlib─1.0.0 (git repo)
   │  └─ ranch─1.0.0 (git repo)
   └─ jiffy─0.14.8 (git repo)

jiffy需要一个不属于rebar的端口编译器插件。您可以在rebar.config中对其进行配置，如下所示：

{plugins, [
    { pc, {git, "git@github.com:blt/port_compiler.git", {branch, "master"}}}
]}.
{overrides,
 [{override, jiffy, [
     {plugins, [pc]},
     {artifacts, ["priv/jiffy.so"]},
     {provider_hooks, [
         {post,
             [
             {compile, {pc, compile}},
             {clean, {pc, clean}}
             ]
          }]
      }
  ]}
]}.

Rebar3不“包括”我的非申请代表
