Unable to locate package python-pytest

Question

I had to reset my machine recently, and so have to re-install everything again.

I want to run a Python file using PyTest.

Bash Terminal:

me@PF2DCSXD:/mnt/c/Users/dabell/Documents/GitHub/workers-python/workers/composite_key/compositekey/tests$ pytest -s test_composite_key.py

Command 'pytest' not found, but can be installed with:

sudo apt install python-pytest

me@PF2DCSXD:/mnt/c/Users/dabell/Documents/GitHub/workers-python/workers/composite_key/compositekey/tests$ sudo apt install python-pytest

I was able to install pip, following this post's Solution.

Please let me know if there is anything else I can add to post.

Answer 1

I had to first install pip, as here:

sudo apt-get update
sudo apt-get upgrade  #Optional
sudo apt install python3-pip

Then

$ pip install pytest
