节点服务器进程在 Ubuntu 服务器上工作，但不在主 Ubuntu PC localhost 上工作
Node server process working on Ubuntu server but not home Ubuntu PC localhost
我正在开发一款小型 MMO，目前在我设置的远程 Ubuntu 服务器上提供服务。在我解决了本地 Node 版本的问题后，服务器进程现在在我的家用计算机上运行良好，但在本地主机上什么也没有出现（除了最初的 Apache 默认页面，但我关闭了 Apache 进程以阻止它阻止端口 80）。我是 运行 使用 node server.js 的代码（好吧，服务器中的 forever server.js，但出于这些目的，它是相同的）。代码如下：
server.js

}

}

return false;
}

this[this.length] = arr[i];
}
String.prototype.leftPad = function (char, length)

var result = this;
while (result.length < length)
{
result = char + result;
}
return result;
}
String.prototype.hashPassword = function (salt)

我在家用 Ubuntu 计算机上尝试了 运行 提升权限的进程并得到：

TypeError: Cannot read property 'prototype' of undefined

有趣的是，我在家用 Ubuntu 机器上降级节点版本之前遇到了同样的错误。
任何关于可能导致此问题的猜测？
我将 EventEmitter.prototype 的所有实例更改为使用 require('events')。然后我将我的节点版本从 6.9.1 版本更新回 7.10.0，我将它降级到（可能没有必要但无论如何都值得做）并且 运行 服务器进程再次作为 root。
现在一切正常。
我正在开发一款小型 MMO，目前在我设置的远程 Ubuntu 服务器上提供服务。在我解决了本地 Node 版本的问题后，服务器进程现在在我的家用计算机上运行良好，但在本地主机上什么也没有出现（除了最初的 Apache 默认页面，但我关闭了 Apache 进程以阻止它阻止端口 80）。我是 运行 使用 node server.js 的代码（好吧，服务器中的 forever server.js，但出于这些目的，它是相同的）。代码如下：

有趣的是，我在家用 Ubuntu 机器上降级节点版本之前遇到了同样的错误。
任何关于可能导致此问题的猜测？
我将 EventEmitter.prototype 的所有实例更改为使用 require('events')。然后我将我的节点版本从 6.9.1 版本更新回 7.10.0，我将它降级到（可能没有必要但无论如何都值得做）并且 运行 服务器进程再次作为 root。
现在一切正常。
