Is there a single line way to run a command in a Python venv?

Question

I have a command that only runs correctly inside a Python virtual environment I've configured (as intended). I know that I can run the command as

$ cmd args

once I've activated the venv. But (due to the constraints of the tool I'm using) I need to activate run (and deactivate?) in one line: something equivalent to running

$ activate_somehow cmd args

outside the command line.

Is there a way to do this?

Answer 1

You can generally run something in a virtual environment simply by using a fully qualified path to the script. For example, if I have:

virtualenv .venv

Then I can install something into that virtual environment without activating it by running:

.venv/bin/pip install foo

This should be true for anything installed using standard Python mechanisms.
