1.》》》執(zhí)行react-native run-ios 報錯
我的操作過程就是：
react-native init myApp
cd myApp
react-native run-ios
出現(xiàn)問題：
** BUILD FAILED **

解決方案：
測試版本：
"react": "16.0.0-alpha.12","react-native": "0.45.0"
切換成下面的版本就可以了：
"react": "16.0.0-alpha.6","react-native": "0.44.3"
具體操作：刪除node-modules文件夾绰精，修改pakage.json文件撒璧，然后執(zhí)行npm install
