推荐答案

我在ubuntu中遇到了同样的问题，对我有用的是关闭的终端从重新启动的usb中删除了我的设备.首先建议您将这些行添加到package.json中，用此替换脚本

i was having the same problem in ubuntu what worked for me is that i closed terminal removed my device from usb restarted. first of all would suggest you add these lines inside your packages.json replace scripts with this

"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"
}

之后，将其保存，然后转到创建项目的文件夹.可以说我的住所/工作区/演示.在该运行脚本中

After that save it and then go to the folder where u created project. lets say mine home/workspace/demo. Inside that run script

npm run clean this will clear all cache

之后

npm run android 

它将在设备以及启动重置缓存中运行应用程序.让我知道它是否有帮助.

It will run app in device as well as start-reset cache.Let me know if it helps.

编辑！！！ 有时添加 在执行npm运行android之前，adb反向tcp:8081做tricj

Edit!!! Sometimes adding adb reverse tcp:8081 before running npm run android does the tricj
