Mac安装homebrew报错curl: (7) Failed to connect to raw.githubusercontent.com port 443: Operation

homebrew安装时，一般直接在终端直接输入命令：

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

但是这个方法在网络有问题时会报如题这个错误。
这个时候直接将文件brew_install.rb下载，然后控制台运行ruby brew_install.rb命令即可。此文件下载地址：
