智能安装逻辑 process_wrap(install_cmd, repo_path) if os.path.exists(install_script_path) and f{repo_path}/install.py not in processed_install: processed_install.add(f{repo_path}/install.py) print(fInstall: install script for {repo_path}) # 执行安装脚本 process_wrap(install_cmd, repo_path, envnew_env)策略一幂等性设计与状态管理企业级节点开发必须确保安装脚本的幂等性即无论执行多少次都不会产生副作用。ComfyUI-Manager通过processed_install集合实现这一目标# 全局已处理脚本集合 processed_install set() def execute_install_script(repo_path): script_id f{repo_path}/install.py if script_id in processed_install: return # 已执行直接返回 processed_install.add(script_id) # 执行安装逻辑状态持久化方案对于需要跨会话保持状态的场景建议在glob/manager_core.py中实现状态持久化class InstallationStateManager: def __init__(self, state_fileinstallation_state.json): self.state_file os.path.join(manager_files_path, state_file) self.state self._load_state() def _load_state(self): try: with open(self.state_file, r) as f: return json.load(f) except FileNotFoundError: return {processed_scripts: []} def mark_processed(self, script_path): if script_path not in self.state[processed_scripts]: self.state[processed_scripts].append(script_path) self._save_state() def is_processed(self, script_path): return script_path in self.state[processed_scripts]策略二依赖冲突智能检测与解决依赖管理是节点开发中最复杂的问题之一。ComfyUI-Manager提供了完善的依赖冲突检测机制def check_dependency_conflicts(requirements): 检查依赖冲突 import pkg_resources conflicts [] for req in requirements: try: pkg_resources.require(req) except pkg_resources.VersionConflict as e: conflicts.append({ package: str(e.req), installed: str(e.dist), required: str(e.req) }) except pkg_resources.DistributionNotFound: pass return conflicts def resolve_conflicts(conflicts): 智能解决依赖冲突 for conflict in conflicts: if conflict[package] in cm_global.pip_downgrade_blacklist: print(f[WARN] 禁止降级关键包: {conflict[package]}) # 记录日志并跳过 log_conflict(conflict) else: # 尝试版本协商 negotiate_version(conflict)虚拟环境隔离策略对于复杂的依赖场景建议使用虚拟环境隔离def create_virtual_env_for_node(node_path): 为节点创建独立的虚拟环境 env_path os.path.join(node_path, .venv) if not os.path.exists(env_path): subprocess.check_call([ sys.executable, -m, venv, env_path ]) #

Windows特定依赖 windows_deps [pywin32, windows-curses] for dep in windows_deps: if not is_installed(dep): install_package(dep) elif platform.system() Linux: # Linux特定依赖 linux_deps [pyinotify] for dep in linux_deps: if not is_installed(dep): install_package(dep)系统路径智能处理不同操作系统的路径处理差异需要特别注意def normalize_path_for_platform(path): 跨平台路径标准化 if platform.system() Windows: # Windows路径处理 path os.path.normpath(path) if not path.startswith(\\\\): path path.replace(/, \\) else: # Unix-like系统路径处理 path os.path.normpath(path) return path def get_executable_path(executable_name): 获取可执行文件路径跨平台 platform_config get_platform_specific_config() suffix platform_config[executable_suffix] if suffix and not executable_name.endswith(suffix): executable_name suffix return executable_name策略四网络优化与镜像源管理针对国内网络环境ComfyUI-Manager提供了镜像源优化策略class MirrorManager: 镜像源管理器 def __init__(self): self.mirrors [ https://pypi.tuna.tsinghua.edu.cn/simple, https://mirrors.aliyun.com/pypi/simple/, https://pypi.douban.com/simple/, https://mirrors.163.com/pypi/simple/, https://pypi.org/simple #
