Enabling monitor mode failed (Kali linux 2.0)

[ondrejmo]

I had downloaded this script and when tried to run script (as root on fresh installed Kali linux 2.0), it gave me this error:

[-] Enabling monitor mode failed, do you have aircrack-ng installed?

My wifi card supports monitor mode (Tp-link tl-wn722n) and when I run:

airmon-ng check kill
airmon-ng start wlan0
...

everything works properly. Can you please tell me how to fix this?
