Python virtual environment (venv)

Python venv Installing Packages

You can run pip by calling the python executable inside the venv folder.

# This installs 'wheel' specifically into that virtual environment
/opt/venv/bin/python -m pip install wheel

Python venv Running Scripts

you can run your Python script by pointing fully to the venv python executable.

/opt/venv/bin/python /path/to/your/script.py

When you run Python this way, it automatically looks for modules inside /opt/venv/lib/pythonX.X/site-packages. It is fully isolated from the system Python.

Python venv Example for Cron

If you wanted to run a script every day at 5 AM via Cron, you would write:

# Correct way (No activation needed)
0 5 * * * /opt/venv/bin/python /home/user/scripts/daily_task.py
