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).
Should I report this issue directly on https://github.com/mkoeppe/sage-numerical-backends-gurobi ? confetti:sage dcoudert$ ./sage -python -m pip install sage-numerical-backends-gurobi Collecting sage-numerical-backends-gurobi Downloading https://files.pythonhosted.org/packages/2c/5c/e1532bb6cde28cf86ebffd408ccb500d7b846bc29bbd1c5e479a2f18acb6/sage_numerical_backends_gurobi-9.0b12.tar.gz Requirement already satisfied: sphinx in ./local/lib/python3.7/site-packages (from sage-numerical-backends-gurobi) (1.8.5) Requirement already satisfied: six>=1.5 in ./local/lib/python3.7/site-packages (from sphinx->sage-numerical-backends-gurobi) (1.12.0) Requirement already satisfied: Jinja2>=2.3 in ./local/lib/python3.7/site-packages (from sphinx->sage-numerical-backends-gurobi) (2.10) Requirement already satisfied: Pygments>=2.0 in ./local/lib/python3.7/site-packages (from sphinx->sage-numerical-backends-gurobi) (2.3.1) Requirement already satisfied: docutils>=0.11 in ./local/lib/python3.7/site-packages (from sphinx->sage-numerical-backends-gurobi) (0.14) Requirement already satisfied: snowballstemmer>=1.1 in ./local/lib/python3.7/site-packages (from sphinx->sage-numerical-backends-gurobi) (1.2.1) Requirement already satisfied: babel!=2.0,>=1.3 in ./local/lib/python3.7/site-packages (from sphinx->sage-numerical-backends-gurobi) (2.6.0) Requirement already satisfied: alabaster<0.8,>=0.7 in ./local/lib/python3.7/site-packages (from sphinx->sage-numerical-backends-gurobi) (0.7.12) Requirement already satisfied: imagesize in ./local/lib/python3.7/site-packages (from sphinx->sage-numerical-backends-gurobi) (1.1.0) Requirement already satisfied: requests>=2.0.0 in ./local/lib/python3.7/site-packages (from sphinx->sage-numerical-backends-gurobi) (2.13.0) Requirement already satisfied: setuptools in ./local/lib/python3.7/site-packages (from sphinx->sage-numerical-backends-gurobi) (40.6.3) Requirement already satisfied: packaging in ./local/lib/python3.7/site-packages (from sphinx->sage-numerical-backends-gurobi) (18.0) Requirement already satisfied: sphinxcontrib-websupport in ./local/lib/python3.7/site-packages (from sphinx->sage-numerical-backends-gurobi) (1.1.0) Requirement already satisfied: MarkupSafe>=0.23 in ./local/lib/python3.7/site-packages (from Jinja2>=2.3->sphinx->sage-numerical-backends-gurobi) (1.1.0) Requirement already satisfied: pytz>=0a in ./local/lib/python3.7/site-packages (from babel!=2.0,>=1.3->sphinx->sage-numerical-backends-gurobi) (2018.7) Requirement already satisfied: pyparsing>=2.0.2 in ./local/lib/python3.7/site-packages (from packaging->sphinx->sage-numerical-backends-gurobi) (2.3.0) Installing collected packages: sage-numerical-backends-gurobi Running setup.py install for sage-numerical-backends-gurobi ... error Complete output from command /Users/dcoudert/sage/local/bin/python3 -u -c "import setuptools, tokenize;__file__='/private/var/folders/l8/sxf193t11mvdyqq56f4w_6_80000gn/T/pip-install-t4k429rc/sage-numerical-backends-gurobi/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /private/var/folders/l8/sxf193t11mvdyqq56f4w_6_80000gn/T/pip-record-sk9om1cp/install-record.txt --single-version-externally-managed --compile: Using GUROBI_HOME obtained from gurobi.sh: GUROBI_HOME is not set, or it does not point to a directory with a Gurobi installation.
