Dear R-help members
Since this morning (5/2/2025), I get an error when I try to load optimx
package. I solve it and I send my solution but if someone has a better
idea or understand what's happened, I will be most happy to know.
MacOSX 15.3
R 4.4.2
nlopt installed using
brew install nlopt
Here are the steps to produce the error and a solution to solve it. Some
parts are in French. I don't know how to "ask" to R to not use French
for some system messages.

Erreur : le chargement du package ou de l'espace de noms a échoué pour

'/Library/Frameworks/R.framework/Versions/4.4-arm64/Resources/library/nloptr/libs/nloptr.so' :
dlopen(/Library/Frameworks/R.framework/Versions/4.4-arm64/Resources/library/nloptr/libs/nloptr.so,

Reason: tried: '/opt/homebrew/opt/nlopt/lib/libnlopt.0.dylib' (no
such file),
'/System/Volumes/Preboot/Cryptexes/OS/opt/homebrew/opt/nlopt/lib/libnlopt.0.dylib'

file), '/Library/Frameworks/R.framework/Resources/lib/libnlopt.0.dylib'
(no such file),
'/Library/Java/JavaVirtualMachines/jdk-11.0.18+10/Contents/Home/lib/server/libnlopt.0.d
It seems that the file libnlopt.0.dylib is not find.
When I check in this folder, indeed it is not present:
√ lib % cd /opt/homebrew/opt/nlopt/lib
√ lib % ls
cmake libnlopt.1.dylib pkgconfig
libnlopt.1.0.0.dylib libnlopt.dylib
I create a symlink:
√ lib % sudo ln -s libnlopt.1.dylib libnlopt.0.dylib
Password:
√ lib % ls -al
