運行環境

操作系統：macOS Sierra 10.12.1
jdk版本：1.8.0_101

項目運行報錯（react-native run-android）

根據網上教程，安裝了安卓運行環境，初始化項目執行react-native run-android

本以為一切會順利，結果報如下錯誤

Failed to notify ProjectEvaluationListener.afterEvaluate(), but primary configuration failure takes precedence.
java.lang.RuntimeException: SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

??但是經過仔細對照?官網和網上資料，發現我的環境并沒有問題，后來在 stackoverflow 上找到了 答案

具體做法是：在項目中 andorid?文件夾下新建一個名為local.properties 的文件
內容寫：

sdk.dir=?你的sdk的路徑

保存后重新運行項目就ok了。
