│ **Unable to locate Gurobi installation. Running some common diagnostics.**
│ 
│ Gurobi.jl only supports the following versions:
│ 
│  - gurobi90
│  - gurobi91
│ 
│ Did you download and install one of these versions from gurobi.com?
│ Installing Gurobi.jl via the Julia package manager is _not_ sufficient!
│ 
│ 
│ We could not find a version of Gurobi in your `PATH`, and we could
│ not find the environment variable `GUROBI_HOME`.
│ 
│ 
│ You should set the `GUROBI_HOME` environment variable to point to the
│ install location then try again. For example (updating the path to the
│ correct location if needed):
│ ```
│ # On Windows, this might be
│ ENV["GUROBI_HOME"] = "C:\\Program Files\\gurobi910\\win64\\"
│ import Pkg
│ Pkg.add("Gurobi")
│ Pkg.build("Gurobi")
│ 
│ # On OSX, this might be
│ ENV["GUROBI_HOME"] = "/Library/gurobi910/mac64/"
│ import Pkg
│ Pkg.add("Gurobi")
│ Pkg.build("Gurobi")
│ 
│ # On Unix, this might be
│ ENV["GUROBI_HOME"] = "/opt/gurobi910/linux64/"
│ import Pkg
│ Pkg.add("Gurobi")
│ Pkg.build("Gurobi")
│ ```
│ **Note: your path may differ. Check which folder you installed the Gurobi
│ binary in, and update the path accordingly.**

Julia should be compatible with Gurobi 9.1 - maybe you just have to update your Julia version?

Please also check where Julia is looking for your Gurobi installation. This is usually done by inspecting the environment variable GUROBI_HOME that is set when installing Gurobi.
