PM2-忽略-监视不工作

Question

我使用pm2已经有一段时间了。最近，我需要向我的Express4项目添加一个名为“ActionLog”的自定义日志目录。因为它是一个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，所以我希望pm2忽略查看该目录。将pm2更新到最新后，下面是我使用的命令：

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

我在pm2日志中得到以下错误流：

PM2 Error: watch ENOSPC

事实证明，尽管这些错误是由忽略监视触发的，但它们并不是由忽略监视引起的。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

我还尝试了“npm dedupe”--就像那个线程上建议的那样--但没有帮助。
