临时解决方案（立即生效但重启失效）
# 查看当前限制值 cat /proc/sys/fs/inotify/max_user_watches# 临时增加限制（推荐值：524288） echo 524288 | sudo tee -a /proc/sys/fs/inotify/max_user_watches永久解决方案（需root权限）
# 编辑系统配置文件 sudo vim /etc/sysctl.conf# 在文件末尾添加（保存后执行sysctl -p生效） fs.inotify.max_user_watches=524288该问题通常发生在大型项目或同时运行多个前端项目时，核心原因是Linux默认文件监视数（通常8192）不足。
