title: After Install Phantomjs Via NPM in Windows 8, Cannot run "phantomjs" command
body: <p>I got problems...
  I'm using npm command from nodejs in my windows 8.1.
  After installation complete, I run npm install -g casperjs, everything goes fine, no error in installment, but nothing happened when I execute casperjs --version command. Cmd said, casperjs is not recognized.
  After that I try to install phantom js using npm install phantomjs command. Everything goes fine too...no error in installment. But when I try to run phantomjs command nothing happened, the cmd said "phantomjs is not recognized.
  I try conventional method for installing casperjs. I'm install phantomjs 1.9.8. Set the path, after that install casperjs 1.1 beta3, set the path...but I got error "casperjs unsafe javascript attempt to access frame with url" message.
  So I got confused...Anyone can help?</p>
