Answer 1

对于Linux:

检查当前值max_user_instances:

$ cat /proc/sys/fs/inotify/max_user_instances

增加这个价值:

$ echo 256 > /proc/sys/fs/inotify/max_user_instances

为了使该更改永久添加一行/etc/sysctl.conf:

fs.inotify.max_user_instances = 256

Answer 2

这通常是一个 linux 配置问题。 增加的文件数量打开的/etc/security/limits.conf：

看起来您使用的是 Mac OS，在这种情况下您应该使用 sysctl。 将以下内容添加到/etc/sysctl.conf：

kern.maxfiles=your new value kern.maxfilesperproc=your new value
