RN 环境搭建

/**
* RN 环境搭建
* 1.创建 Chocolatey
* @powershell -NoProfile -ExecutionPolicy Bypass -Command “iex ((new-object net.webclient).DownloadString(‘https://chocolatey.org/install.ps1‘))” && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin
* 2.创建 Python 2
* choco install python2
* 3.安装NodeJS
* choco install nodejs.install
* 镜像加速
* npm config set registry https://registry.npm.taobao.org –global
* npm config set disturl https://npm.taobao.org/dist –global
* 4.Yarn、React Native的命令行工具（react-native-cli）
* npm install -g yarn react-native-cli
* 镜像加速
* yarn config set registry https://registry.npm.taobao.org –global
* yarn config set disturl https://npm.taobao.org/dist –global
* 5.创建工程
* react-native init AwesomeProject
* 6.运行服务
* react-native start
* （若服务报错TransformError）
* 解决方案
* yarn remove babel-preset-react-native
* yarn add babel-preset-react-native@2.1.0
* 7.服务启动成功访问服务
* http://localhost:8081/index.android.bundle?platform=android
* 8.生成assets
* 新建index.android.bundle文件
* 把http://localhost:8081/index.android.bundle?platform=android内容copy进去即可
* 9.运行
* 10.配置客户端环境
* 摇一摇DevSeting 本地Host端口8081 192.xxx.xx.x:8081
* 11.摇一摇reload
