当我在没有调试的情况下启动sails或仅使用--debug，并包含--verbose作为应用程序参数时，它会向我显示它运行grunt的详细信息（请参阅下面的第一个日志示例）。
但是，当我使用debug-brk =运行应用程序时，它不会运行grunt。 （参见下面的第二个日志示例）。我在一个不同的论坛上发布了这个帖子，并且有人建议＆＃34;很可能grunt是作为子进程生成的，使用相同的调试端口作为父应用程序...而且，由于端口已经绑定，它已被暂停和＆＃34; ＃34 ;.证据似乎支持这一点，但我无法找到grunt模块通过sails模块中的端口的位置。
有没有人遇到过这个？我认为这是一件很平常的事情，而且我错过了一些显而易见的事情。
此致
我正在使用...... 帆0.10.5 节点0.10.29 咕噜0.4.5 grunt-cli 0.1.13
这是一个好运行的例子..没有调试或只有--debug（不是--debug-brk）

答案 0 :(得分：1)
TL; DR - 节点子进程分叉＆＃34; bug＆＃34;让Grunt等待一个永远无法连接的调试器。
Sails使用child_process.fork（）为grunt生成一个单独的进程来运行。
新进程inherits the node command line parameters of the calling process（fork的默认操作）。在你的情况下，＆＃34; - debug-brk＆＃34;。这会导致grunt的节点进程在第一行停止 - 等待调试器连接。
不幸的是，在Windows下，此侦听端口似乎是使用SO_REUSEADDR打开的。这意味着允许两个进程在同一端口上侦听！
在我的测试中，我发现所有连接只打到了第一个开始监听的进程。我永远无法连接到子Grunt进程以允许继续执行。
我听说在新版本的Node（0.15？）中，每个fork都会从base逐步获得自己的端口。但我自己还没有测试过这个。
