钢筋使用时如何处理？ [英] How to handle deps while using rebar to release?

问题描述

我使用 rebar生成来处理发布，但是当我启动
应用程序时，我使用的deps将不会被找到。 >

我可以使用 erl -pa ./ebin ./deps/*/ebin -s myapp 手动启动应用程序。 / p>

我想知道如何配置 rebar.config 和 reltool.config 来处理
依赖关系？谢谢。

解决方案

为了使reltool生成包含依赖关系的版本，您需要将它们添加到 reltool.config 。我有一个名为 drill_instructor 的应用程序，它具有以下 reltool.config 。像 {app，stdlib，[{incl_cond，include}]}，之类的行告诉reltool在发行版中包含该应用程序。我还添加了deps到 lib_dirs 设置。

  {sys， 
 {lib_dirs，[../deps]}，
 {erts，[{mod_cond，derived}，{app_file，strip}]}，
 {app_file，strip}，
 {rel，drill_instructor，1，
 [
内核，
 stdlib，
 sasl，
 crypto，
 ranch，
 jiffy，
牛仔，
 jiffy，
 drill_instructor 
]}，
 {rel，start_clean，，
 [
 
 stdlib 
]}，
 {boot_rel，drill_instructor}，
 {profile，embedded}，
 {incl_cond，exclude}，
 {excl_archive_filters，[。*]}，%%不归档建立的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，crypto，[{incl_cond，include}]}，
 {app， stdlib，[{incl_cond，include}]}，
 {app，kernel，[{incl_cond，include}]}，
 {app，cowboy，[{incl_cond，include}]}，
 {app，ranch，[{incl_cond，include}]}，
 {app，jiffy，[{incl_cond，include}]}，
 {app，drill_armory，[{incl_cond，include}]} ，
 {app，drill_instructor，[{incl_cond，include}，{lib_dir，..}}} 
]}。 
 
 {target_dir，drill_instructor}。 
 
 {overlay，[
 {mkdir，log / sasl}，
 {copy，files / erl，\ {\ {erts_vsn\} \} / bin / erl}，
 {copy，files / nodetool，\ {\ {erts_vsn\} \} / bin / nodetool}，
 {copy ，file / drill_instructor，bin / drill_instructor}，
 {copy，files / drill_instructor.cmd，bin / drill_instructor.cmd}，
 {copy，files / start_erl cmd，bin / start_erl.cmd}，
 {copy，files / install_upgrade.escript，bin / install_upgrade.escript}，
 {copy，files / sys.config ，release / \ {\ {rel_vsn\} \} /sys.config}，
 {copy，files / vm.args，releases / \ {\ {rel_vsn\\ \\} \} /vm.args} 
]}。 
  

在rebar.config中，我还添加了rel作为 sub_dir ：

  {sub_dirs，[rel]}。 
  




I'm using rebar generate to handle release, but when I start the application, the deps I use will not be found.`

I can start the application manually using erl -pa ./ebin ./deps/*/ebin -s myapp.

I'm wonder how to config rebar.config and reltool.config to handle dependencies? Thanks.

解决方案

In order for reltool to generate a release which includes the dependencies, you will need to add them to reltool.config. I have an application called drill_instructor, which has the following reltool.config. The lines like {app, stdlib, [{incl_cond, include}]}, tell reltool to include that application in the release. I also added deps to the lib_dirs setting.

{sys, [
   {lib_dirs, ["../deps"]},
   {erts, [{mod_cond, derived}, {app_file, strip}]},
   {app_file, strip},
   {rel, "drill_instructor", "1",
    [
     kernel,
     stdlib,
     sasl,
     crypto,
     ranch,
     jiffy,
     cowboy,
     jiffy,
     drill_instructor
    ]},
   {rel, "start_clean", "",
    [
     kernel,
     stdlib
    ]},
   {boot_rel, "drill_instructor"},
   {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, crypto,   [{incl_cond, include}]},
   {app, stdlib, [{incl_cond, include}]},
   {app, kernel, [{incl_cond, include}]},
   {app, cowboy, [{incl_cond, include}]},
   {app, ranch, [{incl_cond, include}]},
   {app, jiffy, [{incl_cond, include}]},
   {app, drill_armory, [{incl_cond, include}]},
   {app, drill_instructor, [{incl_cond, include}, {lib_dir, ".."}]}
  ]}.

{target_dir, "drill_instructor"}.

{overlay, [
       {mkdir, "log/sasl"},
       {copy, "files/erl", "\{\{erts_vsn\}\}/bin/erl"},
       {copy, "files/nodetool", "\{\{erts_vsn\}\}/bin/nodetool"},
       {copy, "files/drill_instructor", "bin/drill_instructor"},
       {copy, "files/drill_instructor.cmd", "bin/drill_instructor.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"}
      ]}.

In the rebar.config, I also added rel as a sub_dir:

{sub_dirs, ["rel"]}.
