我使用this guide from fedora在我的Fedora 19上安装了metasploit。完成所有步骤后，我运行 msfconsole 并收到以下错误：
/usr/local/share/ruby/site_ruby/rubygems/specification.rb:1888:in 'method_missing': undefined local variable or method 'ext_dir' for #<Gem::Specification:0xecbd78 json-1.8.0> (NameError)

任何想法如何解决这个问题？它说method_missing：未定义的局部变量或方法“ext_dir”所以这看起来像某种Ruby依赖问题。
更新： msfupdate 成功运行。

您运行的是64位版本的fedora吗？如果是这样，我建议您从rapid7网站下载软件包。它更可靠，安装后任何依赖性问题都将得到解决。使用64bt linux，您还可以将metasploit与Nexpose结合使用。这两个工具携手合作。您看到的问题看起来像版本问题。如果您不介意运行VM，我建议您下载Kali linux以满足您的安全测试需求，这些需求将开箱即用+为您提供更多工具。
