ejabberd開始崩潰

Question

我使用ejabber-14.07和Erlang 17（V6.4），以及更新我的Ubuntu 16.04給我有ejabberd啓動的麻煩之後，它崩潰

{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"]}

{"Kernel pid terminated",application_controller,"{application_start_failure,kernel,{{shutdown,{failed_to_start_child,user,nouser}},{kernel,start,[normal,[]]}}}"} 

我試着找到解決方案，但仍然不知道FOW解決它

Answer 1

我已經創建了自己的名爲「group」的gen_mod，但名稱「group」已經爲本地erlang模塊進行了預留。它試圖使用我的模塊並墜毀。我需要的是模塊的另一個名稱。

Answer 2

的錯誤消息是

{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}]} 
     ]} 

因此它試圖調用group:start(<0.30.0>,{})但沒有定義的功能。您應該先檢查是否有一個名爲group的模塊，它具有一個函數start，該函數接受一個pid和一個元組，並且它的編譯沒有錯誤。
