Cant upload via OTA

[BernH4]

I have the following output:

FQBN       is [esp8266:esp8266:nodemcuv2]

---> Uploading Over The Air
Usage: espota.py [options]

espota.py: error: -f option requires 1 argument
make: *** [Makefile:140: ota] Error 2

This is probably because BINFILE is empty. Honestly its my first time dealing with makefiles but i think it cant find the binary.
Should that BUILD_DIR Variable be a Path? I dont know where that directory is, compiled files still seem to go to /tmp with filename 'arduino-sketch-7EBEE2342ADEAE4BF5085414967AF1EC'
