The `KeyError` means that the `GUROBI_HOME` environment was not set in the shell from which you started Julia. So just set it before starting Julia (probably just add the `export GUROBI_HOME=...` call to `~/.bash_profile` so it’s done automatically).

(See [PSA: how to quote code with backticks](https://discourse.julialang.org/t/psa-how-to-quote-code-with-backticks/7530) for how to properly format code in Discourse by the way).
