运行 Android 在 React Native 上构建时出错
Error While Running Android Build On React Native
我已经安装了所有必要的 SDK 和 Platform Tools。我打开了模拟器，运行，在 PATH 中添加了 adb。这个错误仍然没有让我通过。

请运行在项目文件夹内的终端
export ANDROID_HOME=/Users/{yourusername}/Library/Android/sdk
export PATH=$ANDROID_HOME/platform-tools:$PATH
export PATH=$ANDROID_HOME/tools:$PATH
然后 npm 运行 android
就我而言，我有来自另一个项目的 运行 Metro Bundler。关闭它解决了我的问题。
