Pin with no driver - Kicad
You need Power Flag.

Every time you add a symbol from power library you need to add a power flag.

From documentation:


  It is common to have an error or a warning on power pins, even though all seems normal. This happens because, in most designs, the power is provided by connectors that are not power sources (like regulator output, which is declared as Power out).


Read the whole part about power flags in the link above for more information. This question has been asked millions of times (for instance, here).

By the way, do you have a connector or some other stuff from where your +9 V are actually coming to the IC and other circuitry?
