1阅畴、打開(kāi)本地權(quán)限
sudo chown -R `whoami` /usr/local
2、安裝honebrew
curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local —strip1
3迅耘、檢測(cè)brew是否安裝成功
brew
4贱枣、更新brew
brew update
5、如果4失敗颤专，再次執(zhí)行步驟1纽哥，
Brew update

7栖秕、Node.js直接下載雙擊安裝
8春塌、設(shè)置npm鏡像加速后續(xù)進(jìn)程
npmconfig set registry https://registry.npm.taobao.org --global
npmconfig set disturl https://npm.taobao.org/dist —global
9、安裝Yarn、React Native的命令行工具（react-native-cli）
npminstall -g yarn react-native-cli
設(shè)置鏡像源：
yarn configsetregistry https://registry.npm.taobao.org--global
yarn configsetdisturl https://npm.taobao.org/dist—global
安裝完yarn之后就可以用yarn代替npm了摔笤，例如用yarn代替npm install命令够滑，用yarn add某第三方庫(kù)名代替npm install --save某第三方庫(kù)名。
10吕世、測(cè)試安裝
10.1創(chuàng)建工程
react-nativeinit AwesomeProject
10.2導(dǎo)出成功包
cd AwesomeProject
react-nativerun-ios
11彰触、xcode上運(yùn)行工程時(shí)，要先打開(kāi)服務(wù)器權(quán)限
npm start
12命辖、在index.ios.js中修改代碼
