Mac 运行aapt命令 提示：zsh: command not found: aapt  这个问题是Mac本地没有配置 aapt的 环境变量。理论上本地有Android Studio，aapt是默认配置了的，无奈要用到aapt，还是配置下吧。

mac zsh 配置 aapt 环境变量的方法：

1.在终端输入 open ~/.zshrc 打开zsh环境变量保存的文件。也可以手动去打开

2.进入到Android Studio目录，找到自己 Mac 中 aapt 工具的存放目录：例如我的为：/Users/jason/Library/Android/sdk/build-tools/31.0.0

3.在 .zshrc 文件中添加环境变量配置。

AAPT_HOME=/Users/jason/Library/Android/sdk/build-tools/31.0.0
export AAPT_HOME
export PATH=${PATH}:$AAPT_HOME

4. 然后保存设置：

source ~/.zshrc

5.测试aapt 是否work：

aapt --help

 test result:

Resources that do notmatch this density and have variants that are a closer match are removed.--splitBuilds a separate split APK for the configurations listed. This canbe loaded alongside the base APK at runtime.--feature-ofBuilds a split APK that is a feature of the apk specified here. Resourcesin the base APK can be referenced from the the feature APK.--feature-afterAn app can have multiple Feature Split APKs which must be totally ordered.If --feature-of is specified, this flag specifies which Feature Split APKcomes before this one. The first Feature Split APK should not defineanything here.--rename-manifest-packageRewrite the manifest so that its package name is the package namegiven here.  Relative class names (for example .Foo) will bechanged to absolute names with the old package so that the codedoes not need to change.--rename-instrumentation-target-packageRewrite the manifest so that all of its instrumentationcomponents target the given package.
