  Hi Edmond,

  Can you first make sure you have the latest version of Gurobi.jl installed, and then rebuild the package? The latest Gurobi.jl version right now is 0.11.0, so the sequence of commands in the Julia package manager should be:

  ] update
  ] add Gurobi@0.11.0
  ] build Gurobi

  Type ] to enter the Pkg mode, then type the rest of each line. Also, please ensure the GUROBI_HOME environment variable is set correctly to point to your Gurobi installation.

  Best regards,
  Simon

  Hi Edmond,

  It looks like you are using the older JuMP API (which uses with_optimizer).  You'll need to update your code to use the following method to build a model:

  using JuMP
  using Gurobi
  
  model = Model(Gurobi.Optimizer)

  as outlined in the JuMP example codes.
