Error when building wheels on Linux FileNotFoundError: [Errno 2] No such file or directory: 'ninja'`

Lỗi xảy ra trong quá trình build wheel khi scikit-build-core cố gắng tìm chương trình 'ninja'. Hãy xem Dockerfile hoặc môi trường build để đảm bảo ninja đã được cài đặt. Kiểm tra các dependency build của dự án trong pyproject.toml hoặc setup.py. Bản sửa lỗi có thể sẽ là thêm ninja vào các gói hệ thống trước khi chạy pip install. Xác minh bằng cách chạy một Docker build tối thiểu để cài đặt ninja-build rồi thử chạy pip install.

Prerequisites

Please answer the following questions for yourself before submitting an issue.

• I am running the latest code. Development is very rapid so there are no tagged versions as of now.
• I carefully followed the README.md.
• I searched using keywords relevant to my issue to make sure that I am creating a new issue that is not already open (or closed).
• I reviewed the Discussions, and have a new bug or useful enhancement to share.

Expected Behavior

Please provide a detailed written description of what you were trying to do, and what you expected llama-cpp-python to do.

Current Behavior

Building wheels results in error logs (see below).

Environment and Context

• Docker file, building from ubuntu:jammy
• llama-cpp-python versions tested 0.2.88 and 0.3.2. Behavior consistent.
• Note that I'm still able to build from source directly on my MacOS, so it might be something specific to Linux

Failure Information (for bugs)

I'm unable to build wheels for llama-cpp-python in an ubuntu:jammy base Docker image. I get the error: FileNotFoundError: [Errno 2] No such file or directory: 'ninja'.

Please help provide information about the failure if this is a bug. If it is not a bug, please remove the rest of this template.

Steps to Reproduce

Please provide detailed steps for reproducing the issue. We are not sitting in front of your screen, so the more detail the better.

1. git clone git@github.com:khoj-ai/khoj.git
2. cd khoj && docker build .

You should see the same error reproduced

Here's the pyproject.toml it's using to build: link.

You can see the full error logs in the GitHub Action workflow.

I noticed the ninja project had a release recently, but the error is still consistent if I downgrade ninja to 1.11.1.1.

Our workflow has been running smoothly, and this is the first time we encountered the error (about two hours ago, ~1:00 PM PST). Any help is much appreciated 🙏🏾.
