您将需要Node，React Native命令行界面，JDK和Android Studio。

我以为你有，开发操作系统：Linux，目标操作系统：Android

<强>节点 https://nodejs.org/en/download/package-manager/

React Native CLI

npm install -g react-native-cli

Java开发工具包 http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Android开发环境 https://developer.android.com/studio/index.html

守望者（可选） https://facebook.github.io/watchman/docs/install.html#buildinstall

创建新应用

$ react-native init AwesomeProject

$ cd AwesomeProject

$ react-native run-android

注意：如果你得到如下错误： "unable to load scripts from assets 'index.android.bundle' on real device"

然后，（如果没有创建那么）创建目录为android/app/src/main/assets

旧反应下面的原生版本＆lt; 0.46

$ 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

或

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

然后，

$ react-native run-android

Answer 2

运行此命令

npm install -g react-native-cli

之后，只需将npm路径添加到环境变量

中的系统变量

C:\Users\YOUR USERNAME\AppData\Roaming\npm
