    Hi 奇 钟,

    Using setup.py or pip install is not the recommended method for installing gurobipy when using Anaconda (or miniconda).  Can you see if the approach in the following article works for you?

    How do I use conda to install Gurobi in Anaconda?

    I also would suggest running python -m pip uninstall gurobipy to undo your previous step.
