kompose up fail with unable to build image

I am trying to convert my docker-compose.yml file which works perfectly fine to run it in minikube with kubectl.

I have installed minikube, kubectl and kompose, when I try to run I get the following error:

 C:\Users\test\Downloads\get-string-master\get-string-master> .\kompose-windows-amd64.exe -f .\docker-compose.yml up
INFO Build key detected. Attempting to build and push image 'mainapp'
INFO Building image 'mainapp' from directory 'mainapp'
FATA Error while deploying application: k.Transform failed: Unable to build Docker image for service mainapp: open \tmp\kompose-image-build-399841535: The system cannot find the path specified.

Here is my docker compose file:

version: '3'

services:

mainapp:
    container_name: mainapp
    restart: always
    build: ./mainapp
    image: mainapp
    ports:
        - "8000:8000"

reverseapp:
    container_name: reverseapp
    restart: always
    build: ./reverseapp

    depends_on:

    command: gunicorn -c gunicorn.ini reverseapp.application:app
