Hi Guys,
I'll tell you my story with WPScan and Nokogiri, I hope we can find a solution.
By starting WPScan gave me this error:
drego85@bb-machine:/~$ sudo wpscan
sh: 0: getcwd() failed: No such file or directory

Now I have try to reinstall WPScan:
sudo apt-get install wpscan --reinstall
and it gave me error:

An error occurred while installing nokogiri (1.6.0), and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.6.0'` succeeds before bundling.
dpkg: errore nell'elaborare wpscan (--configure):
il sottoprocesso vecchio script di post-installation ha restituito lo stato di errore 5
Si sono verificati degli errori nell'elaborazione:
wpscan
E: Sub-process /usr/bin/dpkg returned an error code (1)
Ok, I have also tried:
sudo apt-get remove wpscan && sudo apt-get autoremove && sudo apt-get autoclean && sudo reboot
When the system is rebooted I installed WPScan, but it gave me the same error as before.
I think ...Should I install a newer version of Ruby!The command "rvm list" reminds me that I have installed Ruby 1.8, and not the version 1.9.2 request.
Ok, I decided to install the latest version of Ruby!sudo apt-get update
sudo apt-get install git make libcurl4-openssl-dev libopenssl-ruby libxml2 libxml2-dev libxslt1-dev ruby-dev
sudo apt-get install curl
\curl -sSL https://get.rvm.io | bash -s stable --ruby
source ~/.rvm/scripts/rvm
rvm autolibs enable
rvm requirements
rvm list
rvm --default use 2.0.0
Ok,
Now everything must go!sudo apt-get install wpscan
.... .... ....

IS NOT POSSIBLE! 
Ok,
I can try install WPScan by GIT Repository in my HOME folder (It is bold, there is a reason)!
git clone https://github.com/wpscanteam/wpscan.git
cd wpscan
sudo gem install bundler && bundle install --without test development
Beautiful, work everything!But...I can try install WPScan by GIT Repository in original folder /opt/backbox/wpscan:
cd /opt/backbox/
git clone https://github.com/wpscanteam/wpscan.git
cd wpscan
sudo gem install bundler && bundle install --without test development

Why if I installed in the "original” folder Nokogiri goes wrong but if I install it in my home everything is fine?Andrea
PS Sorry for my English...
