这是我尝试过的：
Jaimes-MacBook-Pro:platform-tools jaimemontoya$ pwd
/Users/jaimemontoya/Library/Android/sdk/platform-tools
Jaimes-MacBook-Pro:platform-tools jaimemontoya$ ls
NOTICE.txt deployagent.jar etc1tool make_f2fs sload_f2fs
adb deploypatchgenerator.jar fastboot mke2fs source.properties
api dmtracedump hprof-conv mke2fs.conf sqlite3
deployagent e2fsdroid lib64 package.xml systrace
Jaimes-MacBook-Pro:platform-tools jaimemontoya$ adb shell setprop log.tag.FA VERBOSE
bash: adb: command not found
Jaimes-MacBook-Pro:platform-tools jaimemontoya$
我知道我看到bash: adb: command not found了，但我不确定我是否使用了正确的路径 ( /Users/jaimemontoya/Library/Android/sdk/platform-tools)。请注意，当我使用时，ls我会看到adb列出的内容。那不是目录。这是一个文件，因为当我使用时，我ls -al在权限中看到了这个：-rwxr-xr-x. 这意味着adb是一个文件，而不是一个文件夹。否则，它应该是，drwxr-xr-x但我看到的是-rwxr-xr-x。有什么提示可以帮助我确认我是否adb已在我的 macOS 上安装，以及如何从命令行调用它？

按照 Ashok Chaudhari 在评论中的建议，我从 Android Studio 转到工具 > SDK 管理器 > 外观和行为 > 系统设置 > Android SDK，然后我看到 Android SDK 位置：/Users/jaimemontoya/Library/Android/sdk。我假设adb可以在那个位置找到它，我这样做了：
Jaimes-MacBook-Pro:platform-tools jaimemontoya$ pwd
/Users/jaimemontoya/Library/Android/sdk/platform-tools
Jaimes-MacBook-Pro:platform-tools jaimemontoya$ ls -al

-bash: adb: command not found
Jaimes-MacBook-Pro:platform-tools jaimemontoya$
请注意我仍然收到相同的消息：-bash: adb: command not found. 这对我来说很奇怪，因为adb似乎在那里。
