我在使用钢筋构建我正在处理的erlang应用程序的发行版时遇到了一个奇怪的问题。从本质上讲,它似乎找不到安装在我的系统上的erlang旧款客户端。我可以通过从erlang提示符加载节俭应用程序来验证这一点:
$ erl
Erlang R14B04 (erts-5.8.5) [source] [64-bit] [smp:4:4] [rq:4] [async-threads:0] [kernel-poll:false]
Eshell V5.8.5 (abort with ^G)
1> application:load(thrift).
ok
2> application:loaded_applications().
[{kernel,"ERTS CXC 138 10","2.14.5"},
{thrift,"Thrift bindings","0.9.0-dev"},
{stdlib,"ERTS CXC 138 10","1.17.5"}]
3>
然而,当我尝试运行"钢筋生成"来构建我的应用程序版本时,它失败了:
$ rebar generate
==> rel (generate)
{"init terminating in do_boot","Release fern uses non existing application thrift"}
Crash dump was written to: erl_crash.dump
init terminating in do_boot (Release fern uses non existing application thrift)
这是我的申请文件fern.app.src:
{application, fern, [
{description, "elided"},
{vsn, "0.5.0"},
{modules, [
fern_app,
fern_sup,
accounts_repository,
fern_http_request,
fern_system_api,

metadata_process,

hbase_types,
utils
]},
{registered, [
fern_sup
]},
{applications, [

stdlib,
inets,
ssl
]},
{mod, { fern_app, []}},
{env, []},
{agner, [
{requires, ["jiffy", "meck", "mochiweb"]}
]}
]}.
和我的reltool.config:
{sys, [
{lib_dirs, ["../apps", "../deps"]},
{erts, [{mod_cond, derived}, {app_file, strip}]},
{app_file, strip},
{rel, "fern", "1",

]},

{boot_rel, "fern"},
{profile, embedded},
{incl_cond, exclude},
{excl_archive_filters, [".*"]}, %% Do not archive built libs

{app, crypto, [{incl_cond, include}]},
{app, public_key, [{incl_cond, include}]},
{app, ssl, [{incl_cond, include}]},
{app, thrift, [{incl_cond, include}]},
{app, fern, [{incl_cond, include}]}
]}.
{target_dir, "fern"}.
{overlay, [
{mkdir, "log/sasl"},
{copy, "files/erl", "{{erts_vsn}}/bin/erl"},
{copy, "files/nodetool", "{{erts_vsn}}/bin/nodetool"},
{copy, "files/fern", "bin/fern"},
{copy, "files/sys.config", "releases/{{rel_vsn}}/sys.config"},
{copy, "files/fern.cmd", "bin/fern.cmd"},
{copy, "files/start_erl.cmd", "bin/start_erl.cmd"},
{copy, "files/vm.args", "releases/{{rel_vsn}}/vm.args"}
]}.
我应该注意的是,如果我从这两个版本的应用程序列表中都删除了节俭,那么该版本会生成,但不包括节俭库,因此在运行时会失败。有人能为我在这里做错了什么提供任何指导吗?
非常感谢,
Tim
为了其他遇到这个问题的人,我最终解决了这个问题。出于某种原因,rebar在版本中将"节俭"应用程序重命名为"节俭-0.9.0-dev"。将上述配置中原子"节俭"的所有实例更改为"节俭-0.9.0-dev"(请注意,这是一个原子,而不是字符串-使用单引号)将对其进行排序。
