依赖
sudo apt update
sudo apt install -y git python3-venv python3-dev build-essential aria2| 包 名称 | 用途 |
|---|---|
git | 版本控制工具，用于从 GitHub 上 clone（下载）源码仓库，例如本次使用的 ComfyUI 源码。 |
python3-venv | 用于创建 Python 虚拟环境（python3 -m venv …），可以隔离项目依赖，避免系统 Python 环境和项目依赖冲突。 |
python3-dev | 包含 Python3 的头文件和开发工具，用于编译一些 Python 扩展模块（如有 C/C++ 层绑定时必需）。 |
build-essential | 安装基础编译工具链（如 gcc、g++、make 等），用于编译需要源码编译或构建的依赖。 |
aria2 | 多线程下载工具，常用于从 URL 快速下载大型模型权重或资源（如 .safetensors 等）。 |
创建目录拉取项目代码
可能需要代理，需要魔法。
