AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'? while building openfaas function using: faas-cli

Question

I'm building openfaas function using: faas-cli build -f hello.yml

My YML file is:

version: 1.0
provider:
  name: openfaas
  gateway: http://127.0.0.1:8080
functions:
  hello:
    lang: python3
    handler: ./hello
    image: skum/hello:latest

My requirements.txt has:

boto3
dlib
face_recognition
opencv-python
ffmpeg

While building this YML file in getting the error:

Getting requirements to build wheel did not run successfully.

I have handler.py and requirements.txt in the hello folder where my hello.yml is there, I tried building the faas function using the YML file but got this error. When I keep only boto3 in my requirements.txt file it builds successfully.
