I am not able to get this error as I am new in python. any help highly appreciated

Answer 1

This error basically means you do not have the right installation of python. Some application needs python3.7 and you do not specify a version with apk add python3 . Hence, the latest is probably installed (3.8).

This article deals with how to select a given python version for an agent in a bitbucket pipeline. It basically boils down to:

image: python:3.7
pipelines:
  default:
    - step:
        script:
          - python --version

Is there a reason you have to use Alpine? Otherwise I'd go for the pragmatic image above.

Answer 2

he solve with

pythonRequirements:
   pythonBin: python3
