Error building Gurobi

[oliviagphillips]

I was previously using Gurobi with no issues, and then after I imported a new package Gurobi wouldn't load properly, so I decided to uninstall and reinstall everything. However, the issue hasn't resolved, and I'm getting the following error when I try to build Gurobi again:

julia> Pkg.build("Gurobi") Building Gurobi → ~/.julia/scratchspaces/44cfe95a-1eb2-52ea-b672-e2afdf69b78f/aac05324d46b53289ccb05510b05b4a56ffd3ed5/build.log ERROR: Error building Gurobi: ERROR: LoadError: Unable to locate Gurobi installation. If the advice above did not help, open an issue at https://github.com/jump-dev/Gurobi.jl 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:

• 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 = /Library/gurobi1001/macos_universal2

Does this point to the correct install location?

We're going to look for the Gurobi library in this directory: /Library/gurobi1001/macos_universal2/lib

That directory has the following files:

• /Library/gurobi1001/macos_universal2/lib/gurobi-javadoc.jar
• /Library/gurobi1001/macos_universal2/lib/gurobi.jar
• /Library/gurobi1001/macos_universal2/lib/gurobi.py
• /Library/gurobi1001/macos_universal2/lib/gurobi100.netstandard20.dll
• /Library/gurobi1001/macos_universal2/lib/gurobi100.netstandard20.xml
• /Library/gurobi1001/macos_universal2/lib/libGurobiJni100.jnilib
• /Library/gurobi1001/macos_universal2/lib/libgurobi100.dylib
• /Library/gurobi1001/macos_universal2/lib/libgurobi100_light.dylib
• /Library/gurobi1001/macos_universal2/lib/libgurobi_c++.a
• /Library/gurobi1001/macos_universal2/lib/python3.10
• /Library/gurobi1001/macos_universal2/lib/python3.11
• /Library/gurobi1001/macos_universal2/lib/python3.7
• /Library/gurobi1001/macos_universal2/lib/python3.8
• /Library/gurobi1001/macos_universal2/lib/python3.9
• /Library/gurobi1001/macos_universal2/lib/rootcert.pem

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\\gurobi910\\win64\\"
import Pkg
Pkg.add("Gurobi")
Pkg.build("Gurobi")

# On OSX, this might be
ENV["GUROBI_HOME"] = "/Library/gurobi910/mac64/"
import Pkg
Pkg.add("Gurobi")
Pkg.build("Gurobi")

# On Unix, this might be
ENV["GUROBI_HOME"] = "/opt/gurobi910/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.

What is import Pkg; Pkg.status()? It looks like you have installed an old version of Gurobi.jl.

Try import Pkg; Pkg.pkg"add Gurobi@1".

[oliviagphillips]

Ok it seems like things aren't up to date, but I'm not sure what to do now. I've attached the readouts after trying both of those commands.

(followed by the Stacktrace)

[odow]

Uninstall LightGraphsMatching with import Pkg; Pkg.rm("LightGraphsMatching"), then run import Pkg; Pkg.update().

The package is deprecated and unsupported: https://github.com/JuliaGraphs/LightGraphsMatching.jl

[oliviagphillips]

Gotcha! Ok after doing that, when I run using Gurobi I get the following:

Is this ok? Or do I need to fix something else as well?

[odow]

Try restarting Julia, then run import Pkg; Pkg.update() again. But it looks like it installed the correct version this time.

[odow]

Closing as stale. Things should work fine if you restart Julia.
