Unable to fulfill requirements ortools < 7.0

[danwie]

I'm trying to install ingress fieldplan on a macbook pro (2009) with osx el capitan 10.11.6.

It seems latest ortools is 7.1. Fieldplan requirements is "< 7.0"

I get the following error when trying to install:

$ pip3 install -r requirements.txt

ERROR: No matching distribution found for ortools<7.0 (from -r requirements.txt (line 7))**`

Not sure how to proceed. I've tried editing requirements.txt and remove the version check, but it seems that does not help. When running fieldplan.py I get error.

Could this be related to that I'm using ortools 7.1?

[mricon]

Bah, this is annoying. Yes, the changes in Ortools 7+ are incompatible and I haven't had a chance to port the code to the new codebase yet. It's annoying that they deleted the 6.x distribution.

I'll see if I can prioritize the fix, but for the moment there's not much you can do to get it working, sorry.

[danwie]

Thanks for the reply. Would it be possible to use an old version of ortools? Or are you saying old versions are not available?

[mricon]

Hm... I was actually just able to install it just fine. Which OS are you using?

[danwie]

I'm using osx el capitan 10.11.6. I'm on a vacation and this is a old macbook (2009) that I had to use. On my usual iMac everything is working.

[mricon]

Ah, I can't test things out with OS X, but I would expect it to be sufficiently similar. Can you run:

python3 -m venv tempvenv
source tempvenv/bin/activate
pip install --upgrade pip
pip install -r requirements.txt

If you are still getting that "unable to satisfy" error, then it's possible that ortools-6.x is not available for the combination of OS and Python version that you have on that system.

[danwie]

Thank you for your reply. I still get the same error unfortionately.

$ python3 -m venv tempvenv

I guess I'll have to find someone that can run my google spreadsheet through the script...

Anyway - thanks for helping - and thank you for this script, it's the best (when it's working) :-D

[mricon]

I can run it for you if you pass me the spreadsheet URL and allow worldwide edits to it. :)

[danwie]

Thanks a lot!!
