Problems with running docker image on windows 10

[PlabanKr]

Edition Windows 10 Home Single Language Version 21H1 OS build 19043.1586

I was following instructions from the docs to install and run scancode with docker. Up to building the image, there was no issue, but when I am trying to run the image using docker-compose up scancodeio-worker-1 exits with code 127 and nginx exits with code 1. I have docker desktop installed, and I have installed GNU make with chocolatey in my machine. Here is the terminal message:

@PlabanKr I was also facing the same issue. I fixed it by going to the manage.py file and at the end of the shebang line, just put a space at the end of the python word. This is an error of CRLF/LF.

@PlabanKr @Pratyush1606 any changes we can make in the codebase to fix this issue for good?

A warning about the crlf issue was added in the documentation https://github.com/nexB/scancode.io/commit/37d325a03c02dc5ae9205d4b16eaf729253523ee#diff-d9b149498982c0663c3b7170398773361ed5678f1a627e9c2fd8d2c955c563dbR38-R41
