在mac终端执行homebrew安装命令
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"安装提示
GUOdeMacBook-Pro:~ ****$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)" curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused浏览器直接访问
https://raw.githubusercontent.com/Homebrew/install/master/install.sh将访问的内容拷贝，创建install.sh文件，并保存在本地。
在终端中，cd到install.sh的文件路径，执行
./install.sh安装就会开始了。
