给mac配置安卓环境时报错：

brew install android-platform-tools
Warning: No available formula with the name "android-platform-tools".
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
It was migrated from homebrew/core to homebrew/cask.
You can access it again by running:brew tap homebrew/cask
And then you can install it by running:brew install --cask android-platform-tools
denghui.he@C02GK1A2MD6M ~ % brew tap homebrew/cask
denghui.he@C02GK1A2MD6M ~ % brew install --cask android-platform-tools
Error: Cask 'android-platform-tools' is unavailable: No Cask with this name exists.

按照提示仍然出现最后一个问题，解决方案如下:

brew install Caskroom/cask/android-platform-tools

或者：

brew install --cask  android-platform-tools

安装完成后：将ADB添加到系统环境变量中

export PATH=$PATH:/usr/local/opt/android-platform-tools

重启环境变量，使其生效：

source ~/.bash_profile
