第一步需要在mac上安装brew工具

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

安装成功，出现如下提示

例如：安装ideviceinstaller

brew install ideviceinstaller

安装后的软件，存放在/usr/local/Cellar 目录下　　

 

当运行命令行安装包时报如下错误：

Could not connect to lockdownd. Exiting.

这可能是ideviceinstaller这个工具出现了问题，下面是网上找到的解决方法：

brew uninstall ideviceinstaller

brew uninstall libimobiledevice

brew install --HEAD libimobiledevice

brew link --overwrite libmobiledevice

brew install ideviceinstaller

brew link --overwrite ideviceinstaller
