新建一个文件/tmp/sshpass.rb，写入如下内容，最后执行brew install /tmp/sshpass.rb

require ‘formula’

class Sshpass < Formula
url ‘http://sourceforge.net/projects/sshpass/files/sshpass/1.05/sshpass-1.05.tar.gz’
homepage ‘http://sourceforge.net/projects/sshpass’
sha256 ‘c3f78752a68a0c3f62efb3332cceea0c8a1f04f7cf6b46e00ec0c3000bc8483e’

def install
system “./configure”, “–disable-debug”, “–disable-dependency-tracking”,
“–prefix=#{prefix}”
system “make install”
end

def test
system “sshpass”
end
end
