React Native 解决 Could not get BatchedBridge

本文介绍了解决ReactNative开发中遇到的8081端口被占用的问题,通过查找并关闭占用该端口的程序(如WiFi共享大师),使ReactNative应用能够正常启动。

Windows下做React Native开发,执行react-native run-android后,手机出现红屏提示:
Could not get BatchedBridge, make sure your bundle is packaged correctly

出现这种情况通常是电脑8081端口被占用导致的,因为React Native会在8081端口启动nodejs服务,手机端调试依赖此服务。

可以看看是什么程序占用了8081端口:
1、执行netstat -aon|findstr "8081"

2、看到是8064的程序在监听此端口,再执行tasklist|findstr 8064

可以看到8064进程名是WiFiMaster.exe,原来是WiFi共享大师这货占用了8081端口。

3、关闭WiFi共享大师软件,再执行react-native run-android就可以正常运行了

使用npm install react-native-video-processing@latest后运行有以下报错 D:\AwesomeProject>npm run android > AwesomeProject@0.0.1 android > react-native run-android info Running jetifier to migrate libraries to AndroidX.
