(Preface - I am using rfacebook to integrate my rails app with Facebook. If there's a better option, please let me know. It looks like it hasn't been updated since 2008.)
I installed the rfacebook plugin on windows:
rails plugin install svn://rubyforge.org/var/svn/rfacebook/trunk/rfacebook/plugins/rfacebook
I didn't get any messages. So I assume it installed.
I then ran rake facebook:setup (as per instructions)
I get the following error:
rake aborted!
Don't know how to build task 'facebook:setup'
If anyone has any ideas, I'd be very grateful. Been trying to resolve this for a few hours.
