I am trying to call Julia from Mathematica via ExternalEvaluate, as per this documentation page. I have Julia installed with all the required packages (ZMQ, JSON, and LinearAlgebra), but FindExternalEvaluators["Julia"] still cannot find Julia. The documentation page has no further information. How can I get Mathematica to find my Julia installation? Perhaps it just doesn't know the right place to look?

I solved my issue by making a link to the Julia executable in the directory /usr/bin/. The link had to be named "Julia".

(For anyone trying to do this on a different OS, the way I identified this as the right location was to ask FindExternalEvaluate to look for Python instances--which it successfully found--and note the directory those were located in.)
