How do I resolve the error "Could not open PYTHONSTARTUP"?

The full Gurobi installation packages include a Python distribution to use Gurobi's interactive shell. This can be started using gurobi.sh on Linux and macOS or gurobi.bat on Windows.

If you install Gurobi via Anaconda, i.e. conda install -c gurobi gurobi, you already have a working Python environment, and there is no need for the interactive shell. You can start IPython or a Jupyter notebook for an interactive interface. To test whether a conda package installation and your license file are set up correctly, you should run gurobi_clfrom a command line.

A typical error message when trying to run gurobi.sh with a Gurobi conda package installation is:

Could not open PYTHONSTARTUP
FileNotFoundError: [Errno 2] No such file or directory: '/home/ubuntu/anaconda/lib/gurobi.py'
