需求

1、React Native现在只支持OS X系统

2、Homebrew

　　安装Homebrew：ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"（详情请戳标题）

3、安装Node.js

1. Node.js4.0或者更新
   • 安装nvm参考its setup instructions here

   • vi ~/.bash_profile
     　　添加：source /Users/dujie/.nvm/nvm.sh(需要注意的是将该目录改成自己的目录/Users/dujie)

   • nvm install node && nvm alias default node
   • 或者直接只用brew install node（安装Node）
2. brew install watchman
3. brew install flow

时常运行brew update && brew upgrade来保证本地是最新的项目


4、Xcode6.3或者更高

快速开始

1、npm命令安装React Native 的CLI工具：npm install -g react-native-cli　　

2、创建项目（系统根目录下）：react-native init AwesomeProject(AwesomeProject 是工程名，注：真的是等了好长时间，还以为是哪里出错了，做好心理准备时间有点长)

To run the iOS app:

• $ cd AwesomeProject
• Open ios/AwesomeProject.xcodeproj and hit run in Xcode.
• Open index.ios.js in your text editor of choice and edit some lines.
• Hit ⌘-R in your iOS simulator to reload the app and see your change!

To run the Android app:

• $ cd AwesomeProject
• $ react-native run-android
• Open index.android.js in your text editor of choice and edit some lines.
• Press the menu button (F2 by default, or ⌘-M in Genymotion) and select Reload JS to see your change!
• Run adb logcat *:S ReactNative:V ReactNativeJS:V in a terminal to see your app's logs

Note: If you are using a device, see the Running on Device page.

Congratulations! You've successfully run and modified your first React Native app.

If you run into any issues getting started, see the troubleshooting page.
