我已经运行 npm start、npm run start、sudo npm start 和 sudo npm run start、yarn start、sudo yarn start 并且得到同样的错误：
Loading dependency graph...jest-haste-map: Watchman crawl failed. Retrying once with node crawler.
Usually this happens when watchman isn't running. Create an empty `.watchmanconfig` file in your project's root folder or initialize a git or hg repository in your project.
Error: Watchman error: A non-recoverable condition has triggered. Watchman needs your help!
The triggering condition was at timestamp=1507837337: inotify-add-watch(/home/mohammad/foobar_react_native/node_modules/is-arrayish) -> The user limit on the total number of inotify watches was reached; increase the fs.inotify.max_user_watches sysctl

我怎样才能解决这个问题？
我试过了rm -rf node_modules && npm install.
我试过了
watchman watch-del-all
watchman shutdown-server
