Android工作室：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 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

我没有为这个错误消息突然开始出现做任何事情。是什么导致了这个问题，我该如何解决？安卓工作室版本 3.2.1。

编辑：

错误发生在构建阶段“执行 buildSdkLibs”。完整的错误日志：

TLDR 通过在ovr_sdk_mobile_***/gradle/wrapper 中更改文件gradle-wrapper.properties 将gradle 包装器版本更改为4.7 或更高版本

详情

在构建使用 Oculus VR Api 的项目时，它会运行 VrApp.gradle，而后者又会运行 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，它又运行ovrbuild.py，它又似乎运行一个不同的gradle文件。无论如何，我们感兴趣的错误输出是ovrbuild.py 中的call 函数中的err。 print 语句被android studio吞下了，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，这是因为在 java 9 和 11 之间的某个地方，java -version 的格式发生了变化（请参阅https://github.com/facebook/react-native/issues/22487），并且 gradle 有一段时间无法检测到它。但是，它已在 4.7 版中进行了修补，因此对我而言，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 版本一定是在我没有注意到的情况下更新了。

编辑：正如 cmets 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资源中所说的，但也许它没有在 4.7000 中修补，而是在其他版本 4.7xxx 中修补
