Installation issue

[vcoyne1]

I have tried a number of approaches to install pyopenms on a Win 11 machine. No matter what I do, I get the following error message:

ERROR: Could not find a version that satisfies the requirement pyopenms (from versions: 2.3.0.linux-x86_64, 2.3.0.1.linux-x86_64, 2.3.0.2.linux-x86_64, 2.3.0.3.linux-x86_64) ERROR: No matching distribution found for pyopenms

I would greatly appreciate assistance with this issue.

Thanks, vcoyne

Hi!

Why are you trying to install pyopenms 2.3? This old version is neither supported nor available for Windows.

Hi, I'm not - I get the error messages after running the script "pip install pyopenms".

What python and pip version? 64bit Win or 32bit Win?

[vcoyne1]

I'm running python 3.10.7 and pip 22.2.2 on a Win64 machine

Ah, I see. Python 3.10 is only supported in the nightly versions, for which we do not have a PyPi server yet (@poshul @timosachsenberg).

See the files listed for every version on the public PyPi server: https://pypi.org/project/pyopenms/2.7.0/#files

For nightly installation, please see https://pyopenms.readthedocs.io/en/latest/installation.html#nightly-ci-wheels

Nightly builds' availability is subject to successful builds in our CI.

So it seems that I need to roll back Python to 3.9 to install pyopenms-2.7.0-cp39-cp39-win_amd64.whl. If this works, what will happen if I then re-install Python 3.10?

[jpfeuffer]

You can have multiple python versions installed but pyopenms (stable 2.7) will only be usable and installable within the python 3.9 version.
