運(yùn)行環(huán)境

操作系統(tǒng)：macOS Sierra 10.12.1
jdk版本：1.8.0_101

項目運(yùn)行報錯（react-native run-android）

根據(jù)網(wǎng)上教程，安裝了安卓運(yùn)行環(huán)境，初始化項目執(zhí)行react-native run-android

本以為一切會順利，結(jié)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(jīng)過仔細(xì)對照?官網(wǎng)和網(wǎng)上資料，發(fā)現(xiàn)我的環(huán)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(nèi)容寫：

sdk.dir=?你的sdk的路徑

保存后重新運(yùn)行項目就ok了。
