我有一个简单的项目使用螺纹钢与此配置:
{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"}}
]
}.

(Sorry for the wall)每个依赖项在它的ebin文件夹中都有一个。app文件，我正在运行命令erl -pa apps/*/ebin -pa ebin -pa deps/*/ebin。我希望我应该能够运行application:ensure_all_started(somedep).，其中"somedeep"是在它的ebin文件夹中定义的.app的依赖项的名称。但是当我对它们中的任何一个运行它时，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，_})。因为我不能启动依赖项的应用程序，所以我自己的应用程序失败，出现undef错误。我错过了一些步骤注册我的。app文件与外壳?
Windows命令shell不扩展apps/*/ebin和deps/*/ebin中的通配符，因此没有正确设置Erlang加载路径
