Eleventastic errors on build

[djmtype]

@maxboeck I have no issues when running in dev, but on build I get the error below. Mind you, all I did was clone this repo and didn't touch any files.

I am running an M1 Mac with Node 15.x.

Did you end up finding a solution to this? Having the same issue

I haven't. It's been years since this theme has been updated, too. Another thing that really stands out is the node sass dependency which is deprecated and seems incompatible with Mac ARM chips based on my experience with other projects.
