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.

我在ubuntu中遇到了同样的问题，这对我有用的是，我关闭的终端从USB中删除了我的设备。首先，建议您在包装中添加这些行。JSON用此
替换脚本"scripts": {
"prepare-repository": "npm i -g react-native-cli yarn;yarn install; react-native link",
"emulator": "emulator -avd Nexus5V6L23_x86_64 -scale 1.0",
"install": "react-native run-android",
"start": "react-native start --reset-cache",
"android": "npm run install && npm run start",
"clean": "watchman watch-del-all && npm cache clean && cd android && ./gradlew clean && cd ..",
"test": "jest"
}
保存之后，然后转到您创建的项目的文件夹。假设我的家/工作区/演示。在该运行脚本
中npm run clean this will clear all cache
之后
npm run android
它将在设备中运行应用程序以及启动时缓存。让我知道它是否有帮助。
编辑！！！有时会添加 ADB反向TCP：8081在运行NPM运行Android之前进行TRICJ
