Unable to Install aspose-words in Docker with x86_64 Platform on Mac (Python 3.12)

[KianChavoshiNejad]

Hello,

I’m encountering an issue installing aspose-words (version 25.6.0) inside a Docker container on my Mac (M-series chip). I’ve configured the container to run as linux/amd64 to match our production environment. Here’s the relevant part of my docker-compose.yml:

services:
app name:
platform: linux/amd64
build:
context: .
dockerfile: Dockerfile

The container uses Python 3.12, and I install dependencies using Poetry. However, during docker compose build --no-cache, I consistently receive this error:

Unable to find installation candidates for aspose-words (25.6.0)

at /usr/local/lib/python3.12/site-packages/poetry/installation/chooser.py:74 in choose_for
raise RuntimeError(f"Unable to find installation candidates for {package}")

I’ve verified that the architecture inside the container is x86_64. Still, installation fails, even though documentation and PyPI indicate support for both Mac ARM and Linux x86_64.

could you please let me know how I can fix this issue?

Thank you for your help!
best Regards

@KianChavoshiNejad Since your Mac is on ARM, Linux in docker will also be on ARM. But unfortunately, we do not support Linux ARM.

The key thing is that a Docker container is not a virtual machine: it doesn’t create a new virtual computer on which to run the software. Instead, Docker starts processes in your existing OS, just like you start new processes from the command line.

You can check Multi-platform | Docker Docs where you can find “But containerization by itself only solves part of the problem. Containers share the host kernel, which means that the code that’s running inside the container must be compatible with the host’s architecture.”

We have already registered a WORDSPYTHON-2 request for it and unfortunately, this feature is postponed due to small requests. Sorry for the inconvenience caused.
