Getting an error "pytest: command not found" while running a Python test from CircleCI

Question

I am trying to learn CircleCI but must say, finding it very difficult to use. I am trying to run my Selenium project code written in Python language but getting pytest: command not found error. I have mentioned the PyTest installation in my requirement.txt file, I also tried to install the PyTest by running the below command but still getting the same error.

- run: pip install pytest --user

Here is my config.yml file

version: 2.1

orbs:
  python: circleci/[email protected]


jobs:
  example-job:

    
    docker:
    - image: circleci/python:3.6.1

    
    steps:
      - checkout
      - run: pip install pytest --user
      - python/install-packages:
          args: pytest --user
          pkg-manager: pip
          pypi-cache: false
      - run: 
          command:
            pytest businessObjects/test_Login.py


workflows:
    example-workflow:
      jobs:
        - example-job

Error is

#!/bin/bash -eo pipefail
pytest businessObjects/test_Login.py
/bin/bash: pytest: command not found

Exited with code exit status 127
CircleCI received exit code 127

It must be some basic mistake but tried a lot and am now stuck. Any help is appreciated. Thanks

Finally was able to run my code in CircleCI. Posting my config.yml here in case someone else needs help. Thanks, @jortega for trying to help, appreciate your effort.

version: 2.1
orbs:
  python: circleci/[email protected]
jobs:
  build_and_test: # this can be any name you choose
    executor: python/default
    steps:
      - checkout
      - python/install-packages:
          pkg-manager: pip
      - run:
          name: Run tests
          command: python -m pytest
      - persist_to_workspace:
          root: ~/project
          paths: businessObjects
        - .

    jobs:
      - build_and_test

The easier way to deal with these kind of issue with circleci is to use the option "ReRun job with SSH"

This would allow you to login to the circleci build instance and try out the installation commands

pip install pytest --user

or

python -m pip install pytest

or any command which would fix the issue

The command with which you do not get the error pytest is invalid command , can be used in circleci config
