Question

我有一个使用此配置的钢筋的简单项目：

  {sub_dirs, [
              "gen",
              "apps/basilisk_server",
              "rel"
              "apps/*"
              "ebin"
              "deps/*/ebin"
             ]}.

  {erl_opts, [debug_info, fail_on_warning]}.


  { 
    deps, 
    [
     { email_address, ".*", { git, "git://github.com/mswimmer/erlang-email-address.git", "master"}},

     { gen_smtp     , ".*", { git, "https://github.com/Vagabond/gen_smtp.git"          , "master"}},
     { pat          , ".*", { git, "https://github.com/selectel/pat.git"               , "master"}},
     { thrift          , ".*", { git, "https://github.com/MustyMustelidae/ThriftErl.git", "master"}}
    ]
  }.

我的目录结构是：

            +---.rebar
            +---deps
            |   +---edown
            |   |   +---.rebar

                \---gen <---More source files

（对不起，墙）每个依赖项都有一个.app文件在其ebin文件夹中，我正在运行命令erl -pa apps/*/ebin -pa ebin -pa deps/*/ebin。我希望我能够运行application:ensure_all_started(somedep).其中＆＃34; somedep＆＃34;是在其ebin文件夹中定义了.app的依赖项的名称。但当我为其中任何一个运行它时，我得到错误{error,{somedep,{"no such file or directory","somedep.app"}}}。当我为自己的应用程序运行它时，我得到了正确的响应（{ok，_}）。因为我不能开始依赖＆＃39;应用程序，我自己的应用程序失败，出现undef错误。我错过了一些在shell上注册.app文件的步骤吗？

Windows命令shell不会展开apps/*/ebin和deps/*/ebin中的通配符，因此未正确设置Erlang加载路径。

为什么我的Erlang shell不加载rebar依赖？
