Question

几年后，我想继续与 Erlang / LFE 合作。我有little project是为了学习该语言而设计的。我无法使用rebar3 get-deps命令来获取依赖项。

它遵循 rebar.config ，也here可用。

{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"}}}
  ]}.

我知道我已经引用了 LFE 的旧版本...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。但是，在rebar.config处于其原始状态的情况下，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 macOS Catalina。它遵循 Erlang 环境版本： ERLANG 22.2.1， LFE 1.3， REBAR3 3.12.0。

全部安装有brew。请让我知道是否需要更多详细信息。

我将非常感谢您的帮助。

我最终发现引用lfe/clj和lfe/lhc是多余的，因为这些包是隐式地从其他包中间接正确地引用的。

我已将它们从 rebar.config 中删除，更新为最新语法，并在可能的情况下使用了tag（否则为master）。我将所有URL 切换为使用https://，而不是使用方案git://的SSH。

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"}}}
  ]}.

rebar3无法获取和复制依赖项（LFE项目）
