达到文件观察者数量的系统限制；

错误产生的原因是负责监控 Linux 文件系统的 inotify 程序达到了系统默认的限制上限；

inotify 提供了一种监控文件系统（基于 inode 的）事件的机制，可以监控文件系统的变化如文件修改、新增、删除等，并可以将相应的事件通知给应用程序。

查看 inotify 在内核中的默认配置

uos@uos-PC:~$ sudo sysctl fs.inotify
fs.inotify.max_queued_events = 16384
fs.inotify.max_user_instances = 128
fs.inotify.max_user_watches = 8192

解决方法

临时解决：

sudo sysctl fs.inotify.max_user_watches=100000

永久解决：

echo fs.inotify.max_user_watches=100000 | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

原因是npm淘宝的镜像 https 过期，取消掉严格https验证

npm cache clean --force
npm config set strict-ssl false
