Manjaro Arm Installer Failed

Hi!,
I Used Manjaro-arm-installer script on a Manjaro x86 Budgie, i tried install Raspberry pi 3 lxqt on a SD Card (/dev/mmcblk0) the install wont boot up.
Here the output of the script:
==> Proceeding....
-> Getting package lists ready for rpi3 lxqt edition...
==> Getting /dev/mmcblk0 ready for rpi3...
cat: /sys/block/mmcblk0/mmcblk01/start: No existe el fichero o el directorio
cat: /sys/block/mmcblk0/mmcblk01/size: No existe el fichero o el directorio
expr: syntax error: missing argument after «+»
mount: /var/tmp/manjaro-arm-installer/root: el dispositivo especial /dev/mmcblk0p2 no existe.
==> Creating install for rpi3...
==> Used device is /dev/mmcblk0px
-> Downloading latest aarch64 rootfs...

Seems like wont make the partitions on the SD Card.
Can anyone help?

Thanks for your time!
Regards.
