Run command in different shell without exiting current poetry shell.

[real-yfprojects]

I have written a script that runs a specific build workflow (sphinx) for multiple versions of my project. It copies the contents of specific commits into a temporary directory each and runs the build command there. However I ran into a problem with differing dependencies between versions. The build command itself (sphinx) and its extensions (also python packages) are configured in pyproject.toml.

1. I activate the dev env for my usual development tasks poetry env
2. I run the build script with poetry run my-multibuild-script
3. The build script creates temporary directory (using tempfile) and run poetry in set directory using subprocess: poetry run sphinx-build
4. The build fails because of a missing sphinx-extension set in conf.py and pyproject.toml.

The complete code can be found here.

In general when having any poetry shell activated one cannot run commands in a different shell without exiting.

Not sure if I understand your issue, but if you want to execute a poetry command in another virtual environment while being inside a virtual environment of an outer poetry run you can try to remove "VIRTUAL_ENV" from the env you pass to the subprocess. That way, the inner poetry command will not use the outer environment.

Thanks! That did the trick, although I had to run poetry install in my script before running sphinx with poetry run.

For those coming across this looking for the same thing, here's how I set up the outer environment (though maybe there is a better way?):

import os
import copy
import subprocess

outer_environment = copy.deepcopy(os.environ)
outer_environment.pop("VIRTUAL_ENV", None)

subprocess.Popen(["poetry", "install"], env=outer_environment)
