安装 Brew,网址(https://brew.sh/index_zh-cn.html)

Homebrew能够做什么?

使用 Homebrew 安装 Apple 没有预装但 你需要的东西 。Homebrew 使 macOS 更完整。使用gem来安装 gems、用brew来安装那些依赖包。

$ brew install wget

Homebrew 会将软件包安装到独立目录,并将其文件软链接至 /usr/local

$ cd /usr/local
$ find Cellar
Cellar/wget/1.16.1
Cellar/wget/1.16.1/bin/wget
Cellar/wget/1.16.1/share/man/man1/wget.1

$ ls -l bin
bin/wget -> ../Cellar/wget/1.16.1/bin/wget

Homebrew 不会将文件安装到它本身目录之外,所以您可将 Homebrew 安装到任意位置。

轻松创建你自己的 Homebrew 包。

$ brew create https://foo.com/bar-1.0.tgz
Created /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/bar.rb

完全基于 git 和 ruby,所以自由修改的同时你仍可以轻松撤销你的变更或与上游更新合并。

$ brew edit wget # 使用 $EDITOR 编辑!

Homebrew 的配方都是简单的 Ruby 脚本:

class Wget < Formula
  homepage "https://www.gnu.org/software/wget/"
  url "https://ftp.gnu.org/gnu/wget/wget-1.15.tar.gz"
  sha256 "52126be8cf1bddd7536886e74c053ad7d0ed2aa89b4b630f76785bac21695fcd"

  def install
    system "./configure", "--prefix=#{prefix}"
    system "make", "install"
  end
end
