#全域性安裝 create-react-native-app

yarn global add create-react-native-app

#建立專案

 create-react-native-app  my-app

#安裝ts依賴

yarn add typescript tslint -D   yarn add @types/react @types/react-native @types/react-dom -D

yarn add concurrently rimraf -D

#在根目錄下建立一個tsconfig.json配置檔案，或者tsc --init生成預設配置檔案再修改，把下面程式碼貼上去

#最後最重要的在package檔案中把入口地址修改 "main": "./node_modules/react-native-scripts/build/bin/crna-entry.js"   #把babel.config檔案放在src下面，在src檔案建立ts檔案，開心的寫專案吧   #yarn buildAndStart啟動服務（複合命令）
