mac安裝Homebrew

Homebrew是“MacOS缺失的軟件包管理器”，經常安裝還是比直接下載dmg文件方便些。

可以先試試有沒有安裝過：

brew

-bash: brew: command not found

  打開官網： https://brew.sh/

複製下安裝命令：

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

打開mac終端命令行：

根據terminal的提示進行操作，點擊回車並輸入電腦密碼，如下圖

 

然後等待安裝完之後，會提示：

==> Installation successful!

輸入 brew help 可以查看Homebrew的命令，

Example usage:
  brew search [TEXT|/REGEX/]
