React Native 错误:ENOSPC:达到文件观察者数量的系统限制 [英] React Native Error: ENOSPC: System limit for number of file watchers reached
问题描述
我已经设置了一个新的空白 React Native 应用.
I have setup a new blank react native app.
安装几个节点模块后,我收到此错误.
After installing few node modules I got this error.
Running application on PGN518.
internal/fs/watchers.js:173
throw error;
^
Error: ENOSPC: System limit for number of file watchers reached, watch '/home/badis/Desktop/react-native/albums/node_modules/.staging'
at FSWatcher.start (internal/fs/watchers.js:165:26)
at Object.watch (fs.js:1253:11)

我知道这与没有足够的空间让守望者观察所有文件更改有关.
I know it's related to no enough space for watchman to watch for all file changes.
我想知道在这里采取的最佳行动方案是什么?
I want to know what's the best course of action to take here ?
我是否应该通过将 node_modules
文件夹添加到 .watchmanconfig
来忽略它?
Should I ignore node_modules
folder by adding it to .watchmanconfig
?
推荐答案
Linux 使用 inotify 包以观察文件系统事件、单个文件或目录.
Linux uses the inotify package to observe filesystem events, individual files or directories.
由于 React/Angular 在保存时热重载和重新编译文件,它需要跟踪所有项目的文件.增加 inotify 监视限制应该会隐藏警告消息.
Since React / Angular hot-reloads and recompiles files on save it needs to keep track of all project's files. Increasing the inotify watch limit should hide the warning messages.
你可以尝试编辑
# insert the new value into the system config
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
# check that the new value was applied
cat /proc/sys/fs/inotify/max_user_watches
# config variable name (not runnable)
fs.inotify.max_user_watches=524288
