我试图弄清楚为什么 React Native 突然无法在我的 2014 年 Macbook 上运行。八月初就开始工作了。尝试从命令行运行 react-native run-android 时出现以下错误。当我在 Android Studio 3.0 中打开该应用程序时，它运行得很好，没有错误。有什么想法可以解决这个问题吗？

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

最佳答案
当我在 React-Native Setup Guide 上选择“安装最新的 JDK”时，就发生了这种情况。从字面上看，就是找到最新的 JDK (9) 并安装它。我uninstalled JDK 9并安装了 React-Native 设置指南上链接的 JDK 8 版本，这为我解决了问题。
