执行语句：
brew install lrzsz
详细执行步骤
三、添加iTerm2 trigger
iTerm2 --> Profiles --> Open Profiles --> Edit Profiles --> Advanced --> Edit Trigger
配置项：
Regular expression Action Parameters
\*\*B0100 Run Silent Coprocess /usr/local/bin/iterm2-send-zmodem.sh

如果出错尝试下面这个方法(某高手分享，下面有原始连接)
Running Homebrew as root is extremely dangerous and no longer supported
解决方法
sudo chown -R `whoami` /usr/local/Homebrew/
$ sudo chown -R $(whoami) $(brew --prefix)/*
$ sudo mkdir /usr/local/Frameworks
$ sudo chown -R `whoami` /usr/local/Frameworks/

之后就可以了
sudo chmod 777 文件路径
切换 sudo
sudo su
sudo -i
