How to install or-tools 6.x on osx 10.11.6

[Evmar Hosa]

This is what I've tried. Is there another way? The application I'm using is not compatible with or-tools 7.x yet.

$ pip install --upgrade pip
Requirement already up-to-date: pip in ./tempvenv/lib/python3.7/site-packages (19.1.1)

$ pip install -r requirements.txt
Requirement already satisfied: matplotlib in ./tempvenv/lib/python3.7/site-packages (from -r requirements.txt (line 1)) (3.1.1)
Requirement already satisfied: networkx in ./tempvenv/lib/python3.7/site-packages (from -r requirements.txt (line 2)) (2.3)
Requirement already satisfied: numpy in ./tempvenv/lib/python3.7/site-packages (from -r requirements.txt (line 3)) (1.16.4)
Requirement already satisfied: google-api-python-client in ./tempvenv/lib/python3.7/site-packages (from -r requirements.txt (line 4)) (1.7.9)
Requirement already satisfied: oauth2client in ./tempvenv/lib/python3.7/site-packages (from -r requirements.txt (line 5)) (4.1.3)
Requirement already satisfied: httplib2 in ./tempvenv/lib/python3.7/site-packages (from -r requirements.txt (line 6)) (0.13.0)
Collecting ortools<7.0 (from -r requirements.txt (line 7))
ERROR: Could not find a version that satisfies the requirement ortools<7.0 (from -r requirements.txt (line 7)) (from versions: 7.0.6546, 7.1.6720, 7.2.6977)

Thanks!

You need to pass the version explicitly.

I forgot the exact command line

Thanks.

I've tried

python3 -m pip install --user ortools==6.10.6025

But that didn't work. Maby the binary is no longer available?

[Laurent Perron]

No, but I believe the min requirement in term of osx is higher, like 10.13

I see. That's a bummer. My macbook from 2009 is not able to update to that version of osx.

[Evmar Hosa]

But latest version of or-tools installs without any problem on osx 10.11.6. Wouldn't that imply that or-tools 6.10 also would work with this version of osx?

[Evmar Hosa]

This is the result when trying to install 6.10. Am I doing something wrong?

$ python3 -m pip install --user ortools==6.10.6025
Collecting ortools==6.10.6025

[Laurent Perron]

Yes, we changed the minimum requirements in 7.1

You can still compile from sources. It should be quite easy.
