I don't think you can create symlinks (or something synonymous) on Windows, so this feature is unsupported on that platform. If someone knows better then please help out and send me a pull request ;)
I'll leave this issue open for now, since I think we should have a more friendly error message on platforms that don't support it.
From Windows Vista and onwards there are natively supported symbolic links: http://en.wikipedia.org/wiki/NTFS_symbolic_link#Syntax
Windows XP had something called NTFS junction points which seem similar (not as powerful) but you needed a third party tool: http://support.microsoft.com/kb/205524/en-us
@Marrok are you running Vista or later?
Also, does 'npm link' work for you?
@caolan I am Windows 7.
I've only used npm to install jam, so I can't say for sure.
I've experienced the same issue, but it turned out in my case that I didn't have sufficient permissions. Running the same command as administrator worked... (on Windows 7)
Thanks for the tip robmazan! Permissions was the problem
