Mac 安装brew：brew

安装：

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

出错：

curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused

解决：

• 第一步：把这个网页 传送门 保存名为brew_install.rb的文件，保存的位置你随便，只要自己能找到。
  顺便贴出现有的：

#!/usr/bin/ruby

STDERR.print <<EOS
Warning: The Ruby Homebrew installer is now deprecated and has been rewritten in
Bash. Please migrate to the following command:
  /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

EOS

Kernel.exec "/bin/bash", "-c", '/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"'

• 第二步：在终端输入：curl
  如果打印：curl: try ‘curl --help’ or ‘curl --manual’ for more information 表示就对了。

• 第三步：在终端输入 ：ruby brew_install.rb
