Erlang:rebar生成的包启动失败

Question

每个人。

我有一个由 rebar generate 打包的 erlang 应用程序

这是我的 reltool.config:

{sys, [
   {lib_dirs, ["../../..", "../../deps"]},
   {erts, [{mod_cond, derived}, {app_file, strip}]},
   {app_file, strip},
   {rel, "collector", "1",
    [
     kernel,
     stdlib,
     sasl,
     collector
    ]},
   {rel, "start_clean", "",
    [
     kernel,
     stdlib
    ]},
   {boot_rel, "collector"},
   {profile, embedded},
   {incl_cond, exclude},
   {excl_archive_filters, [".*"]}, %% Do not archive built libs
   {excl_sys_filters, ["^bin/.*", "^erts.*/bin/(dialyzer|typer)",
                       "^erts.*/(doc|info|include|lib|man|src)"]},
   {excl_app_filters, ["\.gitignore"]},
   {app, sasl,   [{incl_cond, include}]},
   {app, stdlib, [{incl_cond, include}]},
   {app, kernel, [{incl_cond, include}]},
   {app, lager, [{incl_cond, include}]},
   {app, goldrush, [{incl_cond, include}]},
   {app, meck, [{incl_cond, include}]},
   {app, mnesia, [{incl_cond, include}]},
   {app, collector, [{incl_cond, include}, {lib_dir, ".."}]}
  ]}.

{target_dir, "collector"}.

{overlay, [
           {mkdir, "log/sasl"},
           {copy, "files/erl", "\{\{erts_vsn\}\}/bin/erl"},
           {copy, "files/nodetool", "\{\{erts_vsn\}\}/bin/nodetool"},
           {copy, "files/collector", "bin/collector"},
           {copy, "files/collector.cmd", "bin/collector.cmd"},
           {copy, "files/start_erl.cmd", "bin/start_erl.cmd"},
           {copy, "files/install_upgrade.escript", "bin/install_upgrade.escript"},
           {copy, "files/sys.config", "releases/\{\{rel_vsn\}\}/sys.config"},
           {copy, "files/vm.args", "releases/\{\{rel_vsn\}\}/vm.args"}
          ]}.

编译打包一切顺利:

但是当我运行应用程序时，它无法启动:

./bin/collector console

错误输出:

Crash dump was written to: erl_crash.dump

内核 pid 终止 (application_controller) ({application_start_failure,lager,{bad_return,{{lager_app,start,[normal,[]]},{'EXIT',{undef,[{erl_syntax,atom,[module], []},{glc_code,abstract_module_,2

似乎主要原因是 {'EXIT',{undef,[{erl_syntax,atom,[module],[]}但我不知道为什么它未定义(我可以手动在控制台中使用它)或如何解决它。

顺便说一句，我使用的是 Erlang R16B02。

有人能帮帮我吗？谢谢。

Answer 1

erl_syntax 是 syntax_tools 的一部分(而不是 erl_parse 可用的标准库)。您需要在钢筋配置中明确添加它，以将其作为收集器版本的一部分包含在内。

{app, syntax_tools, [{incl_cond, include}]},

请注意，rebar.config 中指定的任何内容都会复制到发布文件夹中，并且不会引用已安装的 Erlang 发布。因此需要明确添加许多工具。
