解决途径

iOS 跑步起来react-native run-ios http://www.cnblogs.com/dragon-aslan/p/6965014.html

安卓缺少SDK.dir
SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.
创建local.properties 文件 内容是sdk.dir=/Users/apple/Library/Android/sdk 添加到项目即可

安卓项目运行起来报unable to load script from assets "index.android.bundle”之类的错 之需在 main目录添加创建 assets 文件夹后在终端执行执行
React-native bundle --platform Android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
然后运行 react-native android-run
