ERROR: Could not build wheels for llama-cpp-python, which is required to install pyproject.toml-based projects

[lavenilla]

I'm facing an issue where the wheel for llama-cpp-python fails to build while installing requirements, Has anyone encountered this issue before and managed to resolve it? Any advice or pointers would be greatly appreciated. Thanks!

I had the same problem and asked claude.ai. Got this suggestion and it worked:

Here's a step-by-step approach you can try:

Upgrade pip, setuptools, and wheel: -m pip install --upgrade pip setuptools wheel

Install scikit-build-core: -m pip install scikit-build-core

Try installing the requirements again: -m pip install -r requirements.txt

---

Remember to do it from the python that comes with comfyUI. I made a copy of the bat file to update requirements in the Comfyui_CXH_joy_caption folder and ran it from there. Like so:

@echo off

set SCRIPT_DIR=%~dp0

cd /d "%SCRIPT_DIR%../../../python_embeded"

python.exe -m pip install scikit-build-core

pause

是不是没有安装编译环境啊！如果不想安装完整的 Visual Studio，可以只安装 Build Tools：

• 访问 https://visualstudio.microsoft.com/visual-cpp-build-tools/
• 下载并安装 Build Tools
• 确保选择"C++ 构建工具"选项
