无法在 Android 上通过 Mac OS 编译 mediapipe

如何解决无法在 Android 上通过 Mac OS 编译 mediapipe

我是第一次尝试构建 mediapipe 项目，通读 https://google.github.io/mediapipe/getting_started/android.html，但无法让 bazel 成功完成，到目前为止使用选项 1。

根据错误，dx.jar 文件夹（下方）中缺少文件 /private/var/tmp/_bazel_ted/4a399cb8dd247974fabba333258e1f5f/external/androidsdk/build-tools/31.0.0-rc5/lib。文件名是否已更改为 d8.jar？

-rw-r--r--   1 ted  staff   965K Jun 10 12:54 apksigner.jar
-rw-r--r--   1 ted  staff   5.8M Jun 10 12:54 d8.jar
-rw-r--r--   1 ted  staff    28K Jun 10 12:54 shrinkedAndroid.jar

我更喜欢使用 Android Studio（选项 2），但我使用它的单独构建也失败了。

如果我遗漏了任何有助于确定问题的信息，请告诉我。谢谢。

版本

  • bazel 4.1.0-自制软件
  • Python 3.9.5
  • MacOS Big Sur 11.4
  • ANDROID_HOME = /Users/ted/Library/Android/sdk
  • ANDROID_NDK_HOME = /Users/ted/Library/Android/sdk/ndk/21.4.7075529
  • JAVA_HOME = /Library/Java/JavaVirtualMachines/jdk-12.0.2.jdk/Contents/Home
