Original GitHub issue: https://github.com/Comfy-Org/ComfyUI-Manager/issues/1667

After the update, this error keeps coming up. I changed back to the previous version and it worked fine. Actually, I installed torch and comfyui-frontend-package==1.11.8 correctly.

Try execute this command in your conda environment.

C:\ProgramData\anaconda3\envs\comfyui_svdq\python.exe -s -m pip install comfyui-frontend-package==1.11.8

仍然不能解决，移出这个节点就不会报错，而且功能都正常，放进去就报错。回退版本3.30.8也不会报错

I meant to ask whether the command runs successfully without errors when executed.

I am trying to check whether the issue was caused by adding the -s option. In some environments, problems occur if -s is not included, so it was added.

直接运行确实报错，但是加上它上面写的--user后缀后就能成功运行

I am asking if this error is still occurring.

You should not use system python. The --user option tends to cause more issues in other environments, so I prefer to avoid using it whenever possible.

At the very least, the --user option cannot be used in a venv, and I am unsure what other potential issues it might cause outside of venv.
