failed to install acts_as_ferret plugin

After enter in the command line :ruby script/plugin install svn:// under WIndows XP , nothing happened. I wonder why? Thank you for your help.

any help?

This happens when you dont have svn installed on your system as you can see svn:// at the beginning of the uri which expects you to have svn.

You can check this by just typing svn on your command line.

Grab it from here then everything will work smoothly. Guess the correct version for you is given at the bottom of the page ,
