Erlang无法连接到任何HTTPS网址

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工作正常。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}]}]}}}]}

我在哪里可以找出问题所在？

您缺少ssl Erlang应用程序。一些Linux发行版将Erlang分成几个子包。您应确保在系统上安装了软件包 include PgSearch pg_search_scope :search, associated_against: { current_version: %i(title content) } 。
