ejabberd start在user_drv模块中崩溃

Question

我正在使用ejabber-14.07和erlang 17（v6.4），将我的ubuntu更新到16.04之后，我遇到了ejabberd start的麻烦，它崩溃了

{error_logger,{{2016,8,4},{12,20,35}},"~s~n",["Error in process <0.30.0> on node 'nodeej@marinakr' with exit value: {undef,[{group,start,[<0.30.0>,{}],[]},{user_drv,start_user,0,[{file,\"user_drv.erl\"},{line,154}]},{user_drv,server1,3,[{file,\"user_drv.erl\"},{line,114}]}]}\n"]}
{error_logger,{{2016,8,4},{12,20,45}},crash_report,[[{initial_call,{supervisor_bridge,user_sup,['Argument__1']}},{pid,<0.29.0>},{registered_name,[]},{error_info,{exit,nouser,[{gen_server,init_it,6,[{file,"gen_server.erl"},{line,322}]},{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,237}]}]}},{ancestors,[kernel_sup,<0.10.0>]},{messages,[]},{links,[<0.11.0>]},{dictionary,[]},{trap_exit,true},{status,running},{heap_size,1598},{stack_size,27},{reductions,418}],[]]}

{error_logger,{{2016,8,4},{12,20,45}},crash_report,[[{initial_call,{application_master,init,['Argument__1','Argument__2','Argument__3','Argument__4']}},{pid,<0.9.0>},{registered_name,[]},{error_info,{exit,{{shutdown,{failed_to_start_child,user,nouser}},{kernel,start,[normal,[]]}},[{application_master,init,4,[{file,"application_master.erl"},{line,133}]},{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,237}]}]}},{ancestors,[<0.8.0>]},{messages,[{'EXIT',<0.10.0>,normal}]},{links,[<0.8.0>,<0.7.0>]},{dictionary,[]},{trap_exit,true},{status,running},{heap_size,376},{stack_size,27},{reductions,117}],[]]}
{error_logger,{{2016,8,4},{12,20,45}},std_info,[{application,kernel},{exited,{{shutdown,{failed_to_start_child,user,nouser}},{kernel,start,[normal,[]]}}},{type,permanent}]}
{"Kernel pid terminated",application_controller,"{application_start_failure,kernel,{{shutdown,{failed_to_start_child,user,nouser}},{kernel,start,[normal,[]]}}}"}

我试图找到解决方案，但仍然不知道该如何解决

Answer 1

错误消息是

{undef, [
         {group,start,[<0.30.0>,{}],[]},
         {user_drv,start_user,0,[{file,\"user_drv.erl\"},{line,154}]},
         {user_drv,server1,3,[{file,\"user_drv.erl\"},{line,114}]}
        ]}

因此，它试图调用group:start(<0.30.0>,{})但未定义函数。 您应该首先检查是否有一个名为group的模块，它具有一个带有pid和元组的功能start ，并且正在正确地编译它。

Answer 2

我已经创建了自己的名称为“ group”的gen_mod，但是名称“ group”已经为本地erlang模块保留了。 它试图使用我的模块并崩溃了。 我需要的只是模块的另一个名称。
