几年后，我想回到Erlang/LFE工作。我做了一个小项目来学习这门语言。我无法使用rebar3 get-deps命令获取依赖项。

它遵循rebar.config，也可在此处获得。

{erl_opts, [debug_info, {src_dirs, ["test"]}]}.
{lfe_first_files, []}.
{deps_dir, ["deps"]}.
{eunit_compile_opts, [
   {src_dirs, ["test"]}
  ]}.
{deps, [
   {lfe, "0.9.0", {git, "git://github.com/rvirding/lfe.git", {tag, "v0.9.0"}}},
   {clj, ".*", {git, "git://github.com/lfex/clj.git"}},
   {lhc, ".*", {git, "git://github.com/lfex/lhc.git"}},
   {ljson, ".*", {git, "git@github.com:lfex/ljson.git", "master"}}, 
   {ltest, ".*", {git, "git://github.com/lfex/ltest.git", {tag, "0.4.1"}}}
  ]}.

我知道我引用了旧版本的LFE ...但是如果我删除所有 deps 并尝试再次添加它们：第一个失败的是clj. 但是，rebar.config在原始状态下，我在rebar3 get-deps. 在这里完成输出。

我检查了一个类似的问题和文档，但我仍然无法解决问题。

我的系统是macOS Catalina。它遵循Erlang环境版本： ERLANG 22.2.1、LFE 1.3、REBAR3 3.12.0。

全部安装brew. 如果需要更多详细信息，请告诉我。

我真的很感激任何帮助。

我终于发现引用lfe/clj和lfe/lhc是多余的，因为这些包是从其他包以隐式方式间接和正确引用的。

我已经从rebar.config中删除了这些，更新到最新的语法并tag在可能的情况下使用（否则master）。我将所有 URL切换为使用https://scheme 而不是 SSH git://。

现在我可以rebar3 get-deps使用rebar3 compile.

更新rebar.config：

{erl_opts, [debug_info, {src_dirs, ["test"]}]}.
{lfe_first_files, []}.
{deps_dir, ["deps"]}.
{eunit_compile_opts, [
   {src_dirs, ["test"]}
  ]}.
{deps, [
   {lfe, {git, "https://github.com/rvirding/lfe.git", {"tag", "v1.3"}}},
   {ljson, {git, "https://github.com/lfex/ljson.git", "master"}},
   {ltest, {git, "https://github.com/lfex/ltest.git", {tag, "0.9.0"}}}
  ]}.
