错误:EMFILE:打开的文件太多，请注意，除非我使用 sudo [英] Error: EMFILE: too many open files, watch, unless I use sudo
问题描述
最近我遇到了一个问题.我无法在 element-web 目录中运行 yarn start，我得到了这些 错误.最初我认为它与 element-web 本身有关，所以我创建了一个 问题.一段时间后，我尝试在 bibviz 中运行 wintersmith preview 目录并得到相同的错误.这很奇怪，所以我尝试创建一个 Angular 项目并再次运行 ng serve 和错误.我前往该问题以关闭它，因为它不是 element-web 问题.我发现还有另一个 issue 也有同样的问题.它已经被 turt2live 关闭，说 看起来你已经系统内存不足.基于此，我尝试关闭大多数在后台运行的程序，现在所有命令都可以运行了.
Recently I've run into an problem. I am not able to run yarn start in element-web directory, I get these errors. Originally I thought it had something to do with element-web itself so I created an issue. Some time after that I tried to run wintersmith preview in bibviz directory and got the same errors. This was weird so I tried to create an Angular project and run ng serve and errors again. I headed to the issue to close it as it wasn't an element-web issue. I found that there was another issue created with the same problem. It had already been closed by turt2live saying it looks like you've run out of memory on your system. Based on this I tried to turn of most programs running in the background and now all the commands worked.
我确信 ng serve 过去曾经工作过.
I am sure that ng serve used to work in the past.
我的 PC 有 16 GB 的 RAM，当我使用 7/16 GB 时，命令已经失败.运行命令时我看不到任何内存峰值.使用 sudo 运行命令也完全消除了这个问题.这对我来说没有任何意义.
My PC has 16 GB of RAM and the commands already fail when I am on 7/16 GB. I can't see any memory spikes when running the commands. Running the commands with sudo also completely eliminates the problem. This doesn't make any sense to me.
研究引导我使用 ulimits 但它们似乎没有效果.我也安装了 watchman 没有效果.
Research lead me to ulimits but they seem to have no effect. I have also installed watchman with no effect.
谁能告诉我我错过了什么?
Can someone tell me what I am missing?

推荐答案
我想我已经找到了解决方案:
I think I've found a solution:
- 在
/etc/sysctl.conf中设置限制，添加:
- Set limits in
/etc/sysctl.confby adding:
fs.inotify.max_user_watches=524288
fs.inotify.max_user_instances=512
打开一个新终端或使用
Open a new terminal or reload
sysctl.confvariables withsudo sysctl --system运行
yarn start希望现在一切正常.如果它不起作用，请尝试将限制设置得更高.
Everything should work fine now, hopefully. If it doesn't work try setting the limits higher.
