react native 问题记录

1.

error: bundling failed: "Unable to resolve module `AccessibilityInfo` from `/Users/apple/WebstormProjects/carracing2/node_modules/react-native/Libraries/react-native/react-native-implementation.js`: Module does not exist in the module map\n\nThis might be related to https://github.com/facebook/react-native/issues/4968\nTo resolve try the following:\n  1. Clear watchman watches: `watchman watch-del-all`.\n  2. Delete the `node_modules` folder: `rm -rf node_modules && npm install`.\n  3. Reset packager cache: `rm -fr $TMPDIR/react-*` or `npm start -- --reset-cache`."

最近玩react-native碰到这么个错，解决办法就是关掉node后台进程，用npm start -- --reset-cache命令重新启动packager服务，上面说的所有方法亲试只有这个有效
