【MacOS】brew: command not found

老方式

这种方式已经废弃了：

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

新方式

在线安转

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

本地安装

如果上面命令报错：

curl: (7) Failed to connect to raw.githubusercontent.com port 443: Operation timed out

则直接访问https://raw.githubusercontent.com/Homebrew/install/master/install.sh路径，保存文件本地安装，如图：

拷贝内容保存到本地install.sh文件，然后执行install.sh:

vim install.sh  #拷贝内容
/bin/bash install.sh # 执行安装命令
