My quick-fix solution to this problem would be to add a note to the readme that on windows the -S, --no-symlink option must be used. I just found out that this works without any errors.

Ah interesting… right now I'm checking to see whether the host supports symlinks using hasattr(os, "symlink"), but I guess newer versions of windows do partially support it?

I'd be happy to fix that behavior if there's a better way of detecting whether symlinks are supported.

The symlinks where created when runinng dir2pi on Win10 with admin privileges. The main problem for me is that when using the package index in offline mode the symlinks don't seem to work with pip (again, on Win10), so I had to run it with -S.
