I need help installing.

[meivnae]

I was trying to install on a Windows 10 x64 system but as soon as I write the "python -m pip install opentimeline" command it shows an error. I have python 3.10, I actually uninstalled and reinstalled it after getting the error for the first time to make sure I had the x64 version, but now I don't get what the problem is. Below you can find the terminal output. Thank you in advance.

Hi @RuthlessWinter , pre-built binaries for Python 3.10 haven't been released yet. This means that pip will basically download the source code of OTIO and try t compile it, which is what is failing in your case because CMake can't find a compiler for x64.

You have three options:

1. First one is to use Python 3.9 (which might not be an option for you).
2. Or you can download pre-built binaries from the last build on the main branch that we did. But note that this is an unreleased version of OTIO. See https://github.com/AcademySoftwareFoundation/OpenTimelineIO/actions/runs/2819813841 where at the bottom of the page you will see a wheels file that you can download. Once download, extract it and python -m pip install OpenTimelineIO --no-index --find-links <path to extracted wheels> and that should install the correct package.
3. Configure your environment to have a compiler available so that pip can compile OTIO from source.

I installed python 3.9 and had no problem installing OTIO. Thank you so much!

FYI, OTIO will include pre-built wheels for Python 3.10 in the next release.
