Question

不确定是什么导致了这个问题..昨天工作正常.今天,当我尝试运行react-native run-android时.我收到这个错误.有任何想法吗？

Starting JS server...
Running adb -s 3f71ece6 reverse tcp:8081 tcp:8081
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:

Answer 1

我在尝试在 Ubuntu 上运行在 Windows 上创建的项目时遇到了类似的问题。我找到的解决方案是该gradlew文件project/root/android未设置为可执行文件。所以只需添加一个就chmod +x gradlew可以解决这个问题。
