How to run globally installed coverage on a package inside a virtual enviroment?

Question

I'd like to run a coverage check with the following configuration:

• coverage is installed globally on the system (via pipx).
• pytest in installed inside the virtual environment of the project.

(Inside the venv) When I run coverage run -m pytest I get the error No module named 'pytest'.

How to reproduce

pipx install coverage

python -m venv venv
source ./venv/bin/activate
pip install pytest
coverage run -m pytest

Here are some other outputs (inside the venv)

• command: pytest --version.
  • result: pytest 8.3.4
• command: coverage run --source=. ./venv/bin/python -m pytest
  • result:
    • CoverageWarning: No data was collected.
    • Couldn't run '[...]/venv/bin/python' as Python code: SyntaxError: invalid or missing encoding declaration
