mac osx使用homebrew安装tsocks

tsocks是一款在命令行下为其他软件应用代理的软件。

在mac下使用homebrew安装时会出现找不到formula的问题，homebrew的github上有这个问题的解决方法：

作者给出了formula代码

require 'formula'

class Tsocks < Formula
  # The original is http://tsocks.sourceforge.net/
  # This GitHub repo is a maintained fork with OSX support
  homepage 'http://github.com/pc/tsocks'
  head 'https://github.com/pc/tsocks.git'

  depends_on 'autoconf' => :build if MacOS.xcode_version.to_f >= 4.3

  def install
    system "autoconf", "-v"
    system "./configure", "--prefix=#{prefix}", "--disable-debug", "--disable-dependency-tracking", "--with-conf=#{config_file}"

    inreplace("tsocks") { |bin| bin.change_make_var! "LIBDIR", lib }

    system "make"
    system "make install"

    etc.install "tsocks.conf.simple.example" => "tsocks.conf" unless config_file.exist?
  end

  def test
    puts 'Your current public ip is:'
    ohai `curl -sS ifconfig.me 2>&1`.chomp
    puts "If your correctly configured #{config_file}, this should show the ip you have trough the proxy"
    puts 'Your ip through the proxy is:'
    ohai `tsocks curl -sS ifconfig.me 2>&1`.chomp
  end

  def config_file
    etc / 'tsocks.conf'
  end
end

然后

$ vi /usr/local/Library/Formula/tsocks.rb

复制以上formula代码至此，然后命令行下

$ brew install --HEAD tsocks

安装成功后

$ vi /usr/local/etc/tsocks.conf

添加代码

server = 127.0.0.1 ＃代理地址
server_type = 5    ＃5即socks代理
server_port = 8080 ＃代理端口

然后即可在命令行对任意软件应用代理

$ tsocks wget https://google.com
