Hey @java668! I'm here to help with any issues you're facing. I can assist with bugs, questions, or becoming a contributor. Let's tackle this together!

要解决在运行 make init 时遇到的 faiss-cpu (1.8.0.post1) 不支持 PEP 517 构建以及构建过程中缺少头文件的问题,可以尝试以下步骤:

  1. 添加 pyproject.toml 配置
    在项目根目录下创建或修改 pyproject.toml 文件,添加以下内容以指定构建系统的要求:

    [build-system]
    requires = ["poetry-core", "setuptools", "wheel"]
    build-backend = "poetry.core.masonry.api"

    这将确保在构建过程中可用的必要构建工具,从而解决与 PEP 517 构建和缺少头文件相关的问题[1]

  2. 设置环境变量
    在 macOS 上构建 faiss-cpu 时,可能需要设置环境变量 OBJC_DISABLE_INITIALIZE_FORK_SAFETYYES。可以在运行 make init 之前执行以下命令:

    export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES

    或者在代码中设置该环境变量:

    import os
    import platform
    
    if platform.system() == "Darwin":
        os.environ["OBJC_DISABLE_INITIALIZE_FORK_SAFETY"] = "YES"

    这将避免在 macOS 上运行时出现的错误[2]

  3. 使用 Docker
    如果上述方法仍然无法解决问题,可以考虑使用 Docker 来构建和运行项目。langflow 仓库提供了一个 Dockerfile,可以帮助你绕过 macOS 上的构建问题。以下是 Dockerfile 的内容:

    FROM langflowai/backend_build as backend_build
    
    FROM python:3.10-slim
    WORKDIR /app
    
    RUN apt-get update && apt-get install git -y
    
    COPY --from=backend_build /app/dist/*.whl /app/
    RUN pip install langflow-*.whl
    RUN rm *.whl
    
    EXPOSE 80
    
    CMD [ "uvicorn", "--host", "0.0.0.0", "--port", "7860", "--factory", "langflow.main:create_app" ]

    你可以使用这个 Dockerfile 来构建和运行你的项目[3]

希望这些步骤能帮助你解决问题。

还是安装不了 faiss-cpu (1.8.0.post1)

What I had done temporarily was to remove the caret in pyproject.toml and run poetry lock --no-update to regen the lock.

// remove the caret in pyproject.toml
faiss-cpu = "1.8.0"

// run this to regen the lock.
poetry lock --no-update
