如何在本地跑起来从github上clone下来的react native项目

在一台电脑上做了一个简单的react native的小联系Demo,用的react-native-cli,然后放到了github上,现在在另外一台电脑上把项目clone 下来,npm install后,react-native run-android安装到模拟器上报错,是不是有什么东西需要另外设置呢,这台clone项目的电脑之前跑过react-native的其他项目,是否有影响呢;
现在 报错 app:installDebugException in thread "Device List Monitor" java.lang.NullPointerException
