node.js – pm2 –ignore-watch无法正常工作

我已经使用pm2一段时间了.最近,我需要在我的Express4项目中添加一个名为“actionLog”的自定义日志目录.由于它是一个使用日志文件更新的目录,我不希望pm2在日志文件更改时重新启动应用程序,我希望pm2忽略观看该目录.将pm2更新为最新版后,这是我使用的命令：

pm2 start app.js --watch --ignore-watch="actionLog"

我通过pm2日志得到以下错误：

PM2 Error: watch ENOSPC
PM2     at exports._errnoException (util.js:746:11)
PM2     at FSWatcher.start (fs.js:1172:11)

我也尝试过使用命令：

pm2 start bin/www --watch --ignore-watch="actionLog"

这也产生了同样的错误.

一旦我有正确的ignore-watch参数,我将更新用于启动pm2的json配置文件.目前,将此配置文件与ignore-watch一起使用也会导致错误,但不是如上所述的详细堆栈跟踪,我只在pm2日志中看到以下内容：

PM2: 2016-02-23 04:05:34: Starting execution sequence in -fork mode- for app name:aadm id:2
PM2: 2016-02-23 04:05:34: App name:aadm id:2 online

我查看了一些忽略观察问题的报告,例如：

> https://github.com/Unitech/PM2/issues/1275
> How to auto reload project nodejs use pm2
> Express 4 + pm2 watch not working

不幸的是,我仍然被卡住了.有任何想法吗？

即使错误是由ignore-watch触发的,它们也不是由它引起的.以下命令修复了该问题：

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

我也尝试了“npm重复数据删除” – 这个线程上的建议 – 没有帮助.
