已达到文件观察者数量的系统限制

本文介绍了已达到文件观察者数量的系统限制的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我尝试在 ubuntu 服务器上运行我的项目.命令:

I try to run my project on the ubuntu server.command:

npm run production

它调用

webpack-dev-server --config webpack.prod.js --mode production --inline --progress

构建后我遇到了很多问题:

After it builds I get a lot of issues:

Error from chokidar (/root/galyan/client/node_modules/@material-ui/icons): Error: ENOSPC: System limit for number of file watchers reached, watch '/root/galyan/client/node_modules/@material-ui/icons/index.d.ts'

Error from chokidar (/root/galyan/client/node_modules/@material-ui/icons): Error: ENOSPC: System limit for number of file watchers reached, watch '/root/galyan/client/node_modules/@material-ui/icons/package.json'

网站工作正常，但显示问题:

在本地，我没有看到这个问题.不太明白我接下来应该做什么

On local, I don't see this issue. Not really understand what I should do next

推荐答案

增加文件观察者限制:

Ubuntu 用户(也可能是其他用户)，执行:echo fs.inotify.max_user_watches=524288 |须藤 tee -a/etc/sysctl.conf &&须藤 sysctl -p

(Webpack 文档)

之后，如果错误仍然存​​在，可能需要给一个sudo sysctl --system.

After that, if the error remains, it may be necessary to give a sudo sysctl --system.
