Package Modification Failed

[DesignPrinting]

Package

I want to install the ‘ComfyUi’ on my external SSD, and I don’t know how to select the Data Directory. It seems to always jump back to /Library/Application Support/StabilityMatrix. When I tried to install from Packages>Add Package>ComfyUI and it got “Package Modification Failed” Error. I am using a Mac Studio M2.

When did the issue occur?

Installing the Package

What GPU / hardware type are you using?

Apple M2 Max, Sonoma 14.6.1

What happened?

I tried to re-install the ComfyUI from the Terminal without success. I followed the instructions from LLama 3.2 , and things from bad to worse. The Stability Matrix seems to be my way out. But after installing and re-installing the Stability Matrix, I always got Package Modification Failed. Unpacking resources

, StdErr = ERROR: Could not find a version that satisfies the requirement virtualenv (from versions: none)

} I sincerely hope you can help. I am a newbie and don’t know where to turn to. Thanks
