Mac 安装react-native 环境踩坑记
我的工程创建时间是2019.7.11号下午 ：首先看一下最后我的工程的package.json各个包的版本：
{
"name": "MyApp",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start",
"test": "jest"
},
"dependencies": {
"react": "16.8.3",
"react-native": "0.59.8",
"react-native-gesture-handler": "^1.3.0",
"react-navigation": "^3.11.0"
},
"devDependencies": {
"@babel/core": "^7.5.4",
"@babel/runtime": "^7.5.4",
"babel-jest": "^24.8.0",
"jest": "^24.8.0",
"metro-react-native-babel-preset": "^0.55.0",
"react-test-renderer": "16.8.3"
},
"jest": {
"preset": "react-native"
}
}
1.安装依赖
brew install node brew install watchman 注意 node>10
安装yarn
npm install -g yarn react-native-cli
安装完 yarn 后同理也要设置镜像源：
yarn config set registry https://registry.npm.taobao.org --global
yarn config set disturl https://npm.taobao.org/dist --global
在Appstore下载Xcode 版本>10
React Native 目前需要Xcode 9.4 或更高版本。你可以通过 App Store 或是到Apple 开发者官网上下载。
这一步骤会同时安装 Xcode IDE、Xcode 的命令行工具和 iOS 模拟器。
创建新项目

};
const styles = StyleSheet.create({
scrollView: {
backgroundColor: Colors.lighter,
},
body: {
backgroundColor: Colors.white,
},
sectionContainer: {
marginTop: 32,
paddingHorizontal: 24,
},
sectionTitle: {
fontSize: 24,
fontWeight: '600',
color: Colors.black,
},
sectionDescription: {
marginTop: 8,
fontSize: 18,
fontWeight: '400',

});
export default App;
页面就可以正常出来。
按照官网 需要路由，但是后期如果使用路由组件react-navigation 和react-native-gesture-handler 安装这两个库以后，react-native>=0.6就会出错
这两个的安装按照 官网来 连接 https://reactnavigation.org/docs/zh-Hans/getting-started.html#%E5%AE%89%E8%A3%85
