Could you help me, please?

Maybe the macOS version?

Thank you williaml,
I have BigSur 11.4,

What do you think?

Now that I have another look at it, it doesn't make sense. I don't know.

You should change the title though. The package is called normalregMix.

Thank you Williaml,

I did that. I downloaded that from this GutHub.

No. Change it in the title of the thread.

I did it. I got the same error.
