可以看出是因为缺少 [Android SDK Platform 23]

这时执行android list sdk --all 寻找匹配的序号
执行 android update sdk -u -a -t 53 询问时输入 “y” 并耐心等待

参考

运行时报错

1. 可以试下升级下版本
   react-native upgrade
2. react-native link重复添加了, 手动删除多余的即可
   

   项目根路径 > android > app > src > main > java > com > “你的项目名” > MainApplication.java > protected List getPackages() {// 里面的重复删除}

3. 清除缓存
   react-native start --reset-cache

项目之前运行好好的, 突然不能正常编译了, 报错如下:

error: bundling failed: Error: Unable to resolve module `./babel/runtime/helpers/classCallCheck` from `D:\react-native\m
apDemo\src\router.tsx`: The module `./babel/runtime/helpers/classCallCheck` could not be found from `D:\react-native\map
Demo\src\router.tsx`. Indeed, none of these files exist:

解决方法:

• 删除node_modules文件夹

• package.json： “react”: “16.8.3”, “react-native”: “0.59.2”, “react-redux”: “6.0.1”

• npm安装

node_modules\react-native\scripts\launchPackager.bat和它一样生活node “%~dp0..\cli.js” start

• 改变 @react-native-community\cli\build\commands\runAndroid\runAndroid.js ：

• const procConfig = { cwd: process.cwd() }

• npm cache clean –force

• npm start –clear-cache

• react-native start –reset-cache
  以及我之前完成的这一步

• 删除 C:\Users\YOURUSERNAME\AppData\Local\Temp\metro-cache
