The community member is experiencing an issue when trying to install the llama-cpp-python package using Poetry on Windows. The error message indicates a problem with the build process, specifically related to CMake configuration. The community members suggest that this is likely due to missing dependencies on the Windows system.

The comments provide some guidance, suggesting that the community member should follow the Windows-specific installation instructions for llama-cpp-python, which can be found on the project's GitHub page.

Note: This error originates from the build backend, and is likely not a problem with poetry but with llama-cpp-python (0.2.23) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "llama-cpp-python (==0.2.23)"'.

Seems like an env issue.

My guess is windows is missing some dependencies to install llama-cpp

You can follow windows specific instructions here

I don't quite understand you, if you have some file to edit.

LlamaCPP requires some special installation instructions when installing on windows. Try following the instructions on the link first
