Hi there! I saw on Github that support for the version 10 of Gurobi is added and I just updated to that release of Gurobi; however couldn’t manage to use it in Julia (v1.7.2). I removed the package and added it again after upgrading to Gurobi v10, and when I’m trying to build Gurobi.jl, I get the error below. Would appreciate any help! Thank you!
Error building Gurobi:
ERROR: LoadError: Unable to locate Gurobi installation. If the advice above did not help,
open an issue at GitHub - jump-dev/Gurobi.jl: Julia interface for Gurobi Optimizer and post the full
print-out of this diagnostic attempt.

Unable to locate Gurobi installation. Running some common diagnostics.
Gurobi.jl only supports the following versions:
- gurobi95
- gurobi91
- gurobi90
Did you download and install one of these versions from gurobi.com?
Installing Gurobi.jl via the Julia package manager is not sufficient!
Found GUROBI_HOME = C:\gurobi1000\win64
Does this point to the correct install location?
We’re going to look for the Gurobi library in this directory:
C:\gurobi1000\win64\bin
That directory has the following files:
- C:\gurobi1000\win64\bin\Gurobi100.NET.XML
- C:\gurobi1000\win64\bin\Gurobi100.NET.dll
- C:\gurobi1000\win64\bin\GurobiJni100.dll
- C:\gurobi1000\win64\bin\grb_ts.exe
- C:\gurobi1000\win64\bin\grbcluster.exe
- C:\gurobi1000\win64\bin\grbgetkey.exe
- C:\gurobi1000\win64\bin\grbprobe.exe
- C:\gurobi1000\win64\bin\grbtune.exe
- C:\gurobi1000\win64\bin\gurobi.bat
- C:\gurobi1000\win64\bin\gurobi100.dll
- C:\gurobi1000\win64\bin\gurobi100_light.dll
- C:\gurobi1000\win64\bin\gurobi_cl.exe
- C:\gurobi1000\win64\bin\vslauncher.exe
- C:\gurobi1000\win64\bin\vswhere.exe
We were looking for (but could not find) a file named like
libgurobiXXX.so, libgurobiXXX.dylib, or gurobiXXX.dll.
You should set the GUROBI_HOME environment variable to point to the
install location then try again. For example (updating the path to the
correct location if needed):
# On Windows, this might be
ENV["GUROBI_HOME"] = "C:\\Program Files\\gurobi950\\win64\\"
import Pkg
Pkg.add("Gurobi")
Pkg.build("Gurobi")
# On OSX, this might be
ENV["GUROBI_HOME"] = "/Library/gurobi950/mac64/"
import Pkg
Pkg.add("Gurobi")
Pkg.build("Gurobi")
# On Unix, this might be
ENV["GUROBI_HOME"] = "/opt/gurobi950/linux64/"
import Pkg
Pkg.add("Gurobi")
Pkg.build("Gurobi")
Note: your path may differ. Check which folder you installed the Gurobi
binary in, and update the path accordingly.
