git.exc.GitCommandError: Cmd('git') failed due to: exit code(128)
cmdline: git clone -v -- https://github.com/ltdrdata/ComfyUI-Manager ./ComfyUI/custom_nodes/comfyui-manager
stderr: 'fatal: destination path './ComfyUI/custom_nodes/comfyui-manager' already exists and is not an empty directory.

Start with the reported ComfyUI installation command and the path ./ComfyUI/custom_nodes/comfyui-manager. Inspect how the manager installation handles an existing non-empty destination, then reproduce the GitCommandError; done means the installation behavior or user-facing guidance clearly accounts for this condition.
