Unable to install on windows

[ReelChezburger]

When attempting to install using 'pip3 install opentimelineio' I get the error:

ERROR: Command errored out with exit status 1: 'd:\hprograms\python\python.exe' -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'D:\\TEMP\\pip-install-vdx134eo\\opentimelineio\\setup.py'"'"'; __file__='"'"'D:\\TEMP\\pip-install-vdx134eo\\opentimelineio\\setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' install --record 'D:\TEMP\pip-record-q9kmgkfc\install-record.txt' --single-version-externally-managed --compile --install-headers 'd:\hprograms\python\Include\opentimelineio' Check the logs for full command output.

I have just installed both python and CMake.
in the middle there is also the error:

DEPRECATION: Could not build wheels for opentimelineio which do not use PEP 517. pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. A possible replacement is to fix the wheel build issue reported above. You can find discussion regarding this at https://github.com/pypa/pip/issues/8368.

Arg, sorry about that.

Which version of python are you using?

tagging @meshula and @reinecke since they've worked on this stuff a bit.

[meshula]

There's some crucial information lacking, before we can help out.

• is msvc installed, what version?
• is python installed, and in the path, what version (the only clue in the error is pip3, so I can guess python 3.x)
• what steps did you follow to build, are they the steps we describe in the documentation?

1. I have MSVC 2005, 2008, 2010, 2012, 2013, and 2015-2019
2. I installed Python 3.8.5, and added it to PATH
3. I instaled PySide2 using pip install PySide2 as described in the quickstart guide, then ran pip install opentimelineio

I uninstalled opentimelineio, deleted my pip cache, and under Python 3.8.0, VS2019, I got a successful installation.

I'm wondering if you could delete your pip cache, run the pip install opentimelineio command again, and paste the full log here?

Ah! A clue!! It appears you have installed a 32 bit version of Python, but we have selected a 64 bit build for OTIO. So first, there is likely a bug in our configuration, but second, did you actually intend for a 32 bit build?

that appears to be the issue, meant to install the 64bit version but didn't. It now works. Thanks for the help!

Just one more note -- we technically don't support python 3.8, but it might work fine. We aren't running it through our CI at present though.
