gem packetfu LoadError

Question

我正在嘗試使用packetfu寶石。我是紅寶石新手，所以請耐心等待。我用ruby-1.9.3-head [x86_64]來使用rvm。我也有Mac OSX版10.7.4試圖運行sudo的紅寶石應用程序/模型時，我收到此錯誤/ simpleSniff.rb

/Users/aragorn/.rvm/rubies/ruby-1.9.3-head/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- packetfu (LoadError) 
from /Users/aragorn/.rvm/rubies/ruby-1.9.3-head/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require' 
from app/simpleSniff.rb:2:in `<main>' 

中包含的simpleSniff.rb代碼

#!/usr/bin/env ruby 
require 'packetfu' 

include PacketFu 
iface = "eth1" 

cap = Capture.new(:iface => iface, :start => true) 
cap.stream.each do |p| 
put p 
end

gem 'sqlite3' 

Answer 1

A）的要求問題特別是因爲你sudo'ing而不是rvmsudo'ing（這將保持在機智你的Ruby環境）

B）如果PacketFu和Pcaprub和注射和捕獲所有適用於您的OS X機器，請讓我知道！我會感到震驚和敬畏。我聽說謠言對一些人來說很有效。不過，我從來沒有親眼看到過它。
