fatal error: 'gurobi_c.h' file not found

dcoudert commented 4 years ago

I have an error when trying to install the gurobi backend that is now a separate optional package. I followed the instructions for installing the gurobi backend with sage 9.1.beta0 and macOS Mojave 10.14.6. I have gurobi 8.11 and gurobi.sh is in my path (so no need to set GUROBI_HOME). (note that I successfully installed the cplex backend).

confetti:sage dcoudert$ ./sage -python -m pip install sage-numerical-backends-gurobi
