poetry install location

[blnprasad]

I'm trying to build docker with python3.9 and poetry1.2 version. I'm installing packages using below command.
poetry config virtualenvs.create false && poetry install --without dev

looks like poetry installing packages under directory ( ./usr/local/lib/python3.8/dist-packages/httpx) and
my sys path is coming as below
sys.path = [
'/',
'/usr/lib/python39.zip',
'/usr/lib/python3.9',
'/usr/lib/python3.9/lib-dynload',
'/root/.local/lib/python3.9/site-packages',
'/usr/local/lib/python3.9/dist-packages',
'/usr/lib/python3/dist-packages',
]

since installed directory is not under sys path the packages being ignored. i didn't see this issue with 3.8(/usr/local/lib/python3.8/dist-packages/). can you help what's going wrong here?

When you install with Poetry into system site-packages, the site-packages selected by Poetry will correspond to the interpreter running Poetry.

Try running poetry debug info and you should discover which interpreter Poetry is running with.

Note that virtualenvs.create is usually a footgun and you do not want to mix your project in with the system Python packages -- you may break your package manager, break Poetry (if installed through OS packaging), experience instability as Poetry is not the only thing managing your Python environment, or run into OS-supplied packages that are incompatible with the Python packaging ecosystem.

What problem are you trying to install by installing into system site-packages?

I went with that option since it docker container to run my server alone. i'll check more on that

Installation into system site-packages is an antipattern in most containers -- a virtual environment doesn't just isolate your code from other Python code, but from the operating system and other tools (like Poetry) as well. Please see #6397 (comment) for a pattern you can try in your Dockerfiles, and #6398 for additional context.
