I have both Racket and Jupyter installations running fine with even after installing zeromq with the commands given, I'm getting the following error on Mac OS Mojave :

I'm on Catalina and experiencing the same issue. I've had Jupyter up and running (with a variety of language kernels) for months and installed Racket minutes before trying to get the current version of iRacket up and running.

I solved this problem by copying /usr/local/Cellar/zeromq/4.3.3/lib/libzmq.5.dylib to /Applications/Racket\ v8.1/lib/.

I installed both Racket and zeromq with homebrew on MACOS Catalina 10.15.7 The problem is Racket's search path

BTW I assume a link from /Applications/Racket\ v8.1/lib/ to /usr/local/Cellar/zeromq/4.3.3/lib/libzmq.5.dylib would work as well.

This solves the problem for me as well. I'm using Mac OS Mojave 10.14.6. Make sure to update the final path based on Racket version.

I am not a fan of copying files installed by a package manager to other places on the system. It clutters up your drive and can lead to issues when trying to uninstall. IMO a better approach is to chance the lib-search-dir racket uses to find dynamic libraries. This can be achieved by something like:

cat /Applications/Racket\ v8.3/etc/config.rktd
#hash(
(build-stamp . "") 
(catalogs . ("https://download.racket-lang.org/releases/8.3/catalog/" #f)) 
(doc-search-url . "https://download.racket-lang.org/releases/8.3/doc/local-redirect/index.html") 
(lib-search-dirs . (#f "/opt/homebrew/lib")))
