rebar3 无法获取和复制依赖项（LFE 项目）

Question

几年后我想回到 Erlang/LFE 工作。我有一个 little project 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，也可以使用here。

{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 dep 并尝试再次添加它们：第一个失败的是 clj。然而，rebar.config 处于原始状态，我在rebar3 get-deps 之后得到了以下输出。完成输出here。

我检查了similar question 和documentation，但仍然无法解决问题。

我的系统是 ma​​cOS Catalina。它遵循 Erlang 环境版本： ERLANG 22.2.1，LFE 1.3，REBAR3 3.12.0。

全部使用brew 安装。如果需要更多详细信息，请告诉我。

非常感谢任何帮助。

我终于发现引用lfe/clj 和lfe/lhc 是多余的，因为这些包被其他包以隐式方式间接且正确地引用。

我已将这些从 rebar.config 中删除，更新为最新语法并尽可能使用tag（否则master）。我将所有 URL 切换为使用 https:// 而不是 SSH 和方案 git://。

现在我可以使用 rebar3 get-deps 获取依赖项并使用 rebar3 compile 进行编译。

更新了 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"}}}
  ]}.
