android - 构建失败，出现异常 java.io.IOException : Permission denied

Question

我正在尝试让 React Native 项目在我的 Linux Mint PC 上运行，但我很难做到这一点，因为我收到以下错误消息:

据我所知，这与 gradle 的权限有关，我尝试了以下方法:

chown -R username ./android/gradlew
chmod 777 -R ./android
chmod +x ./android/gradlew

但这些似乎都不能解决我的问题。如果有人能在这里帮助我，我将不胜感激。

Answer 1

试试这个:

1 - 构建 gradle。如果没有问题，请继续访问应用程序的 android 文件夹。即 c:\folder\app\android

2 - 输入 ./gradlew clean

3 - 运行react-native run-android
