sqlite-vec cannot be installed via uv on Windows ("No executables are provided by package")

I'd appreciate any suggestions.

try uv add sqlite-vec , the tool command is for binary tools, sqlite-vec is a library

[sgtkt]

Unfortunately, it does not seem to work this way.

> uv add sqlite-vec
error: No `pyproject.toml` found in current directory or any parent directory

The sqlite-vec library comes with the "Basic Memory" app installed per the guidelines.

> uv tool install basic-memory
Resolved 145 packages in 838ms
Installed 145 packages in 4.16s
 + aiofile==3.9.0
...
 + sqlalchemy==2.0.49
 + sqlite-vec==0.1.9         <--- !
 ...
 + zipp==3.23.1
Installed 2 executables: basic-memory, bm

Which later reports this issue somewhere.

The Basic Memory author actually has this issue described as "Python 3.13 Compatibility" in the first-time-setup.md file, but reverting to Python 3.12.0 does not change the situation.

There are Windows wheels published for your platform, and available on pypi: https://files.pythonhosted.org/packages/1e/c8/662276c01c39aca7dfe6b05712270394a9a61963289007034249d81a4de7/sqlite_vec-0.1.10a1-py3-none-win_amd64.whl#sha256=f0419b764fd8aa87cd990c5ad2c579563f1a6be05e063e40ef12c38a130f718e

Your logs show that sqlite-vec==0.1.9 is successfully installed, so I actually think the problem is that your Python version has SQLite extension loading disabled. Can you try:

uv tool install --managed-python basic-memory

This will instead use a version of Python from the uv team instead of the one you have installed

[sgtkt]

I've uninstalled the Windows Store version of Python and tried multiple different versions of Python, but none seem to make any difference.

• https://www.python.org/ftp/python/3.12.0/python-3.12.0-amd64.exe + uv tool install basic-memory
• uv python install cpython-3.12.0-windows-x86_64-none + uv tool install --managed-python basic-memory

Here's what I have now.

I'm starting to think that maybe the root cause is in the sqlalchemy library, which cannot load sqlite-vec as an extension. Is it a valid concern?
