React Native之react-native run-android运行命令报错问题解决

报错如下：

Starting JS server...

Building and installing the app on the device (cd android && ./gradlew installDebug...

Could not install the app on the device, read the error above for details.

Make sure you have an Android emulator running or a device connected and have set up your Android development environment: https://facebook.github.io/react-native/docs/android-setup.html

 

解决方案：

若一切环境都配置好，且android手机设备已连接，那么可以尝试以下来确保权限是否足够

在项目的终端中添加以下命令：

chmod 755 android/gradlew

即可，亲测可行。
