Failed to locate nib in stylus file

Question

I am trying to use Nib CSS3 extensions in stylus. Installed stylus and nib (tried local & global -g). But none works, when I do

stylus styles.styl > build/styles.css

# styles.styl
@import "nib"

I get

/usr/lib/node_modules/stylus/bin/stylus:502
              throw err;
                    ^
Error: styles.styl:1
 > 1| @import "nib"
   2| 
   3| body 
   4|   background: linear-gradient(top, white, black)

failed to locate @import file nib.styl

Yes I think I missed out the -u flag as @Jonathan pointed out
