文件观察者数量超过系统限制

2022年06月16日就是一些笔记

症状1

在系统文件管理器中新建文件时不会自动刷新。

症状2

启动Angular项目报了如下错误：

Watchpack Error (watcher): Error: ENOSPC: System limit for number of file watchers reached, watch '/home/daizc/IdeaProjects/beam/beam-frontend/src/main/angular/node_modules/@webcomponents/webcomponentsjs'
Watchpack Error (watcher): Error: ENOSPC: System limit for number of file watchers reached, watch '/home/daizc/IdeaProjects/beam/beam-frontend/src/main/angular/node_modules/@webcomponents'
Watchpack Error (watcher): Error: ENOSPC: System limit for number of file watchers reached, watch '/home/daizc/IdeaProjects/beam/beam-frontend/src/main/angular/node_modules/@types/trusted-types'
Watchpack Error (watcher): Error: ENOSPC: System limit for number of file watchers reached, watch '/home/daizc/IdeaProjects/beam/beam-frontend/src/main/angular/node_modules/@types'

解决方案:A

React Native Error: ENOSPC: System limit for number of file watchers reached

经验证，重启后会失效

1 2	`sudo sysctl fs.inotify.max_user_watches=524288 # 我自己设置的是131072 sudo sysctl -p`

解决方案:B

Inotify 监视限制 (Linux)

将以下行添加到/etc/sysctl.conf文件或目录下的新*.conf文件（例如idea.conf）/etc/sysctl.d/:
fs.inotify.max_user_watches = 524288
然后运行此命令以应用更改：
sudo sysctl -p --system

系统环境:

OS: Deepin 20.6 apricot
