ComfyUI启动报错ModuleNotFoundError: No module named 'requests'求助

问题场景 #

执行启动命令：

(Comfyui) E:\Comfyui\ComfyUI>python main.py --directml

出现ModuleNotFoundError: No module named 'requests'错误，完整报错日志如下：

已尝试执行pip3 install requests，反馈requests已安装，但问题未解决。

解决方案 #

• 强制在当前环境安装requests
  你当前激活的是Comfyui虚拟环境，pip3可能指向全局Python环境，用以下命令确保在当前环境重新安装：

  (Comfyui) E:\Comfyui\ComfyUI>python -m pip install requests --force-reinstall
  

• 验证当前环境的requests安装状态
  执行命令查看当前环境已安装包列表，确认requests存在：

  (Comfyui) E:\Comfyui\ComfyUI>pip list
  

  若列表中无requests，重复上一步的强制安装命令。

• 修复huggingface_hub依赖
  报错触发点是导入huggingface_hub时的requests缺失，重新安装该包：

  (Comfyui) E:\Comfyui\ComfyUI>python -m pip install huggingface_hub --force-reinstall
  

• 重装ComfyUI全部依赖
  若以上步骤无效，直接重新安装项目所有依赖，确保版本兼容：

  (Comfyui) E:\Comfyui\ComfyUI>python -m pip install -r requirements.txt --force-reinstall
