无法在具有 Apple M1 芯片的最新 macbook 上加载 R package gmm

Question

I'm trying to load package gmm (running "library(gmm)") and get this error message below.

It seems unfixable, as it states that my gfortran/lib/libgomp.1.dylib has the wrong architecture? I'm guessing this is related to the new Mac architecture?

library(gmm) Loading required package: sandwich

Error: package or namespace load failed for 'gmm' in dyn.load(file, DLLpath = DLLpath, ...):

unable to load shared object '/Library/Frameworks/R.framework/Versions/4.0/Resources/library/gmm/libs/gmm.so':

dlopen(/Library/Frameworks/R.framework/Versions/4.0/Resources/library/gmm/libs/gmm.so, 6): Library not loaded: /usr/local/gfortran/lib/libgomp.1.dylib Referenced from: /Library/Frameworks/R.framework/Versions/4.0/Resources/library/gmm/libs/gmm.so

Reason: no suitable image found. Did find:

**/usr/local/gfortran/lib/libgomp.1.dylib: mach-o, but wrong architecture**
/usr/local/gfortran/lib/libgomp.1.dylib: mach-o, but wrong architecture

I had the same issue on R version 4.1. Found a similar question here which points to installing (or updating) your gfortran installation here . Once I did that and restarted R, the gmm package was able to find the missing image(s) automatically when I loaded the package.
