无法在 Ubuntu 16.04 上安装 net-keepalive 模块答案

【问题标题】：Unable to install net-keepalive module on Ubuntu 16.04无法在 Ubuntu 16.04 上安装 net-keepalive 模块
【发布时间】：2016-08-16 04:04:04
【问题描述】：

我可以在我的 MAC 操作系统上安装 net-keepalive 模块，但不知道为什么我不能在我的 Ubuntu 16.04 上安装。我想使用这个模块的原因是 node.JS 网络模块关闭事件没有按我的预期工作，TCP 服务器拔出 Etghernet 电缆需要一段时间才能执行关闭事件。我想要的是我的节点服务器能够在 TCP 服务器以太网电缆拔出或断电时进行判断。如果 net-keepalive 模块无法在 Ubuntu 上安装，我将非常乐意听到任何其他建议。

报错信息如下：

【问题讨论】：

你也sudo apt-get install nodejs-legacy了吗？您似乎缺少 node 符号链接。
您好 mscdex，非常感谢。有效。这是我的第一台 Ubuntu 机器，没有意识到它需要符号链接，你可以重新发布你的评论作为答案吗？我标记为答案。谢谢~~~

【解决方案1】：

在 Ubuntu/Debian 上，如果您通过软件包管理器从普通发行版存储库安装 node.js，您还需要安装 nodejs-legacy 软件包，该软件包将添加常用的 node 可执行符号链接（而不仅仅是拥有nodejs 可执行文件）。
