Above it says that with a noun it should be:  

avoir besoin de/d' + (article) + noun

but then below it says:  

Verbal phrases like avoir besoin de don't use the definitive article (or partitive article).

These seem contradictory.  If I want to say: 

"You need flour" 

Do I say:  "Tu as besoin de farine"   or   "Tu as besoin de la farine"

Could someone please clarify with respect to both countable and uncountable items.
