Uploading Picovaders to my Nano

Hi. I made a quick Arduboy clone with my Nano and 3 buttons. How do I upload Picovaders to it? Because every time it tells me this: Error during Upload: compiled sketch not found in /tmp/duino-137hhvV939ErzU/picovaders_hex_ino/build/arduino.avr.uno
btw it says uno because I always select uno board when uploading to my nano (it only uploads when I do it). Any fix?
