Using python 3.8 but importing pytest from 2.8 instead of 3.8

I'm using python 3.8 but pytest keeps getting imported from 2.7 These are my commands:

python3.8 -m venv venv
. ./venv/bin/activate
pip3.8 install --upgrade pip
pip3.8 install -U pytest
pip3.8 install -r requirements.txt

Then I check:

(venv) xxx@xxx:~/Documents/my-dashboard$ pytest --version
This is pytest version 3.3.2, imported from /usr/lib/python2.7/dist-packages/pytest.pyc

Why is pytest imported from 2.7 version if my environment is using 3.8? How do I import pytest from 3.8?

Solution

  • If you’re installing with python3.8 and pip3.8 you should run with:

    python3.8 -m pytest

    Your default python on your path seems to be 2.7, so you need to change your PATH or be explicit about which python you want to run.
