用debug-brk启动Sails不会运行Grunt？
当我没有debugging或仅使用–debug启动sails，并且包含–verbose作为应用程序参数时，它会显示它运行的grunt的详细信息（请参阅下面的第一个日志示例）。
但是，当我用debug-brk =运行应用程序时，它不会运行grunt。 （请参阅下面的第二个日志示例）。 我发布了这个在不同的论坛，有人build议“最可能的咕噜生成一个subprocess使用相同的debugging端口作为父应用程序…而且，由于端口已经绑定，它已被暂停”。 证据似乎支持这一点，但我无法find咕噜模块越过sails模块中的端口的位置。
有没有人遇到过这个？ 我会认为这会是一件普通的事情，我错过了一些明显的东西。

这是一个很好的运行的例子..没有debugging或只有–debug（不是–debug-brk）

TL; DR – 一个Nodesubprocess分叉“bug”让Grunt等待一个永远不能连接的debugging器。
Sails使用child_process.fork（）来产生一个单独的进程，以便运行grunt。
新进程inheritance调用进程的节点命令行参数 （fork的默认操作）。 在你的情况下，“–debug-brk”。 这会导致grunt的节点进程在第一行停止 – 等待debugging器连接。
不幸的是，在Windows下，这个监听端口似乎是用SO_REUSEADDR打开的。 这意味着两个进程被允许在同一个端口上侦听！
“第二个套接字成功绑定后，绑定到该端口的所有套接字的行为是不确定的。”
在我的testing中，我发现所有的连接只会触发第一个开始监听的进程。 我永远不能连接到孩子Grunt进程，以允许执行继续。
我听说在更新版本的节点（0.15？）中，每个分支将从基地递增地获得自己的端口。 但是我没有自己testing过。
