ノードサーバプロセスはUbuntuサーバで動作しますが、ホームはありませんUbuntu PC localhost

Question

現在、私は遠隔のUbuntuサーバIセットアップで提供されている小さなMMOに取り組んでいます。ローカルのNodeバージョンで問題を修正した後、サーバプロセスは自宅のコンピュータで正常に動作するようになりましたが、localhostには何も表示されません（最初はApacheのデフォルトページを除きますが、Apacheプロセスを閉じてポート80をブロックしません）。私はnode server.jsを使用してコードを実行しています（サーバーではforever server.jsですが、目的は同じです）。コードは以下の通り：

    return (this.substr(0, prefix.length) == prefix); 
} 

String.prototype.contains = function (toSearch)

    return (this.indexOf(toSearch) != -1); 
} 

Array.prototype.inArray = function (obj) 
{ 
    for (var i = 0; i < this.length; i++) 
     if (this[i] == obj) 
      return true; 
    return false; 
} 

Array.prototype.append = function (arr) 
{ 
    for (var i = 0; i < arr.length; i++) 
     this[this.length] = arr[i]; 
} 

String.prototype.leftPad = function (char, length) 
{ 
    var result = this; 
    while (result.length < length) 
    { 
     result = char + result; 
    } 

    return result; 
}

は、私は家のUbuntuコンピュータ上の特権でプロセスを実行して取得しようとした：興味深いことに、私は家のUbuntuマシン上のノードのバージョンをダウングレードする前に、私はなっていた、同じエラーでした

sudo node server.js 
[sudo] password for peter: 
/home/peter/cubicverse-new/server/node_modules/socket.io/lib/store.js:35 
Store.prototype.__proto__ = EventEmitter.prototype; 

TypeError: Cannot read property 'prototype' of undefined 
    at Object.<anonymous> (/home/peter/cubicverse- 
new/server/node_modules/socket.io/lib/store.js:35:41) 

。

これを引き起こしている可能性はありますか？

Answer 1

EventEmitter.prototypeのすべてのインスタンスを代わりにrequire('events')に変更しました。それから、ノードのバージョンをバージョン6.9.1から7.10.0に更新しました。これをダウングレードしましたが（おそらく必ずしも必要ではありませんが、やりがいのある価値があります）、ルートとしてサーバープロセスを再実行しました。

すべて正常に機能しています。
