missing wheel for pysimstring (Python 3.11+); failed to build leveldb on Windows

[valentin-marie]

The last wheel for https://pypi.org/project/pysimstring/1.2.1/ is for Python 3.10, so the uv package manager fails to install medkit-lib with Python 3.11+. Or I would need administrator rights on Windows, or building from source on Linux.

So I installed medkit-lib[hf-utils,training] v0.16.0 using uv with Python 3.10 on Windows.

I failed to install medkit-lib[all] using uv with Python 3.10 on Windows, I get an error message.

 uv add medkit-lib[all]
  × Failed to build `leveldb==0.201`
  ├─▶ The build backend returned an error
  ╰─▶ Call to `setuptools.build_meta:__legacy__.build_wheel` failed (exit code: 1)

      [stderr]
      Don't know how to compile leveldb for Windows!

      hint: This usually indicates a problem with the package or the build environment.
  help: `leveldb` (v0.201) was included because `predibilia` (v0.1.0) depends on `medkit-lib[all]` (v0.16.0) which depends on `quickumls>=1.4` (v1.4.2) which depends on `leveldb>=0.193`

If I install plyvel-wheels with uv first, then attempt the install of medkit-lib[all], I get the same error message.

This may be related to #60.

Meanwhile, I hope medkit-lib[hf-utils,training] will be enough.

Thank you for your work.

Not exactly. Getting leveldb to work on Windows is notoriously challenging. Even plyvel, the alternative backend I proposed using in my PR to QuickUMLS, does not have working wheels for Windows yet.

In the meantime, you should probably try using WSL for developing with medkit, or ssh to a Linux server. I don't think either the issues on plyvel and QuickUMLS are going to be resolved any time soon. It looks like maintenance of the latter is on a stand still.

Thank you!
