Do I need to keep .watchmanconfig file in react-native project

问题 default react native project generates .watchmanconfig file that is simply empty object {} , can I safely delete this? A subquestion would be: is there any watchman configuration I can do / refference to improve react-native project experience somehow? 回答1: .watchmanconfig can be safely deleted. If Watchman does not find the .watchmanconfig relative to your root directory, then it will simply load the watchman configuration present in /etc/watchman.json in your global configuration.

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

问题 I have setup a new blank react native app. After installing few node modules I got this error. I know it's related to no enough space for watchman to watch for all file changes. I want to know what's the best course of action to take here ? Should I ignore node_modules folder by adding it to .watchmanconfig ? 回答1: You could try editing echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p cat /proc/sys/fs/inotify/max_user_watches fs.inotify.max_user_watches

the command `brew install watchman` runs `chmod` but fails to install eventually

问题 I've made an app with react native - create-react-native-app. Initially npm start worked fine. But now npm start get's stuck at Starting Packager. A few days ago, deleting the node_modules folder and reinstalling npm dependencies and then doing npm start seemed to work. But now even that doesn't work. Any help will be appreciated npm -v 6.0.0 node -v v10.0.0 react-native-cli: 2.0.1 react-native: 0.54.0 os - Ubuntu 16.04 回答1: The issue was in the /proc/sys/fs/inotify/max_user_watches = 8192

Why “Watchman crawl failed” error in react-native immediately after updating to macOS catalina?

问题 Trying to run react-native run-ios or build RN project from xcode, as soon as metro bundler starts, this error appears in the terminal: 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.
