Docker Images firos exited with code 127

[iasonasiasonos]

Hello,
I am using Desktop Docker in order to install firos. I am following the tutorial and i am getting the followint error message and firos docker image cannot run.

firos | /usr/bin/env: ‘python\r’: No such file or directory
firos exited with code 127

The steps i am following in order to install firos in a Docker image are:

1. git clone --recursive https://github.com/iml130/firos.git
2. docker-compose up

Do i need to do enything else to make this work?
Thank you!
