Erlang 无法连接到任何 HTTPS url

Question

当我尝试构建 rebar3 时出现问题，但它无法从 Amazon S3 获取其依赖项。调试问题我发现 erlang 运行时无法连接到任何 HTTPS 站点，尽管 curl 或 wget 工作得很好。当我设置 httpc:set_options([{verbose,trace}]) 时，我得到以下输出：

    {failed_connect,
              [{to_address,{"s3.amazonaws.com",443}},
               {inet,
                   [inet],
                   {eoptions,
                       {undef,
                           [{ssl,connect,
                                ["s3.amazonaws.com",443,
                                 [binary,
                                  {active,false},
                                  {ssl_imp,new},
                                  inet],
                                 20000],
                                []},
                            {http_transport,connect,4,
                                [{file,"http_transport.erl"},{line,135}]},
                            {httpc_handler,connect,4,
                                [{file,"httpc_handler.erl"},{line,891}]},
                            {httpc_handler,
                                connect_and_send_first_request,3,
                                [{file,"httpc_handler.erl"},{line,905}]},
                            {httpc_handler,init,1,
                                [{file,"httpc_handler.erl"},{line,242}]},
                            {proc_lib,init_p_do_apply,3,
                                [{file,"proc_lib.erl"},{line,239}]}]}}}]}

我在哪里可以找到问题所在？

您缺少 ssl Erlang 应用程序。一些 Linux 发行版将 Erlang 分成几个子包。您应该确保您的系统上安装了软件包 erlang-ssl。

Erlang 无法连接到任何 HTTPS url

Erlang can't connect to any HTTPS url
