React-Native搭建报错:Unable to load script.Make sure you're either running a metro server or that ....
报错
Unable to load script.Make sure you're either running a metro server
(run 'react-native start' ) or that
your bundle 'index.android.bundle' is packaged correctly for release.
原因
我自己这里报错原因是没有找到index.android.bundle。
解决方法
方法一
创建android/app/src/main/assets文件夹
执行命令
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
重新执行
react-native run-android

方法二
修改 项目目录/android/app/build.gradle里

主要是设置bundleInDebug等于true,使得开发时也会打包index.android.bundle。
