情景

在新建立的ReactNative專案，執行命令：react-native init Hello
在專案資料夾下執行react-native run-ios，但是出現以下報錯：

Command /bin/sh failed with exit code 1

原因分析

init命令預設會建立最新的版本，而目前最新的0.45版本需要下載boost庫編譯。此庫體積龐大，在國內即便翻牆也很難下載成功，導致很多人無法正常執行iOS專案，推薦暫時使用0.44.3的版本。

解決方法

建立專案暫時先使用react-native init MyApp –version 0.44.3，指定某個版本。
你可以使用–version引數（注意是兩個槓）建立指定版本的專案。例如react-native init MyApp –version 0.44.3。注意版本號必須精確到兩個小數點。
