Android studio：进程'命令'python''以非零退出值1完成

Question

我一直在使用 android studio 为 OculusGO 进行开发。它一直工作正常，但现在突然我的 android studio 项目拒绝构建，我只收到错误消息：

Process 'command 'python'' finished with non-zero exit value 1

我没有做任何事情，这个错误消息突然开始出现。是什么导致了这个问题以及如何解决它？Android Studio版本3.2.1。

编辑：

该错误发生在构建阶段“执行 buildSdkLibs”。完整错误日志：

TLDRgradle-wrapper.properties通过更改以下 文件将 gradle 包装器版本更改为 4.7 或更高版本ovr_sdk_mobile_***/gradle/wrapper

细节

当构建使用 Oculus VR Api 的项目时，它会运行 VrApp.gradle，而 VrApp.gradle 又会运行 python 脚本。这个 python 脚本失败了，这就是错误的来源。运行的 python 脚本是bin/scripts/ovrbuild_sklibs.py，它依次运行ovrbuild.py，而后者又似乎运行不同的 gradle 文件。无论如何，我们感兴趣的错误输出是errincall函数中的ovrbuild.py。print 语句被 android studio 吞没了，所以要么你必须以某种方式从命令行运行 gradle （我猜，但我不太了解 gradle），但我只是通过编辑 python 脚本将错误保存到文件中。错误信息是

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '11.0.2'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

这似乎是一个众所周知的错误，它来自于 java 9 和 11 之间的某个事实，格式发生了java -version变化（参见https://github.com/facebook/react-native/issues/22487），并且 gradle 是一时无法察觉。但是，它在 4.7 版本中进行了修补，所以对我来说，解决方案是将 gradle 包装器版本更改为更高版本（不是 android studio 中的 gradle 版本，而是 gradle-wrapper.properties 中指定的版本）。我不知道为什么这个错误突然出现在我身上，但可能我的java版本一定在我没有注意到的情况下已经更新了。

编辑：正如评论指出的，更改为 4.8 或更高版本，我写了 4.7，因为这是他们在在线源中所说的，但也许它没有在 4.7000 中修补，而是在其他版本 4.7xxx 中修补
