no method available for opening http localhost 8000
Hi there, I was trying to open the notebook interface from the Sage Shell command line. But after I typed in 'notebook()', a message pops up like ... no method available for opening 'http://localhost:8000'. Can anyone tell me what that means and how to fix it? Thanks a lot!
I am running on Windows 7 and using virtualbox as vm. I never used linux before. So any help would be great.
