Hello,
First of all, sorry for the bad title, but I sincerely have no idea what this error is about...

I am a long time maxfield user and have created (and executed) a lot of maxfields over the past years. I even do them when on vacation and I have some spare time...

OK, that's not my issue..

The script was running fine until "something" changed on my system...

I am running Manjaro Linux so the problem is most probably some BC issue, That's just one of the reasons I hate Python...

So here is the output:

maxfield-plan /path/to/waypoints.txt --outdir /path/to/dir --num_agents 1 --output_csv --num_cpus 0 --num_field_iterations 100 --max_route_solutions 100 --skip_step_plots --verbose > /path/to/log.txt

Traceback (most recent call last):
  File "/usr/bin/maxfield-plan", line 4, in <module>
    __import__('pkg_resources').run_script('maxfield==4.0', 'maxfield-plan')

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'maxfield==4.0' distribution was not found and is required by the application

Since this looks oh so pythonic, I decided to go the windows way and just reinstalled the thing with python setup.py install and at least the error changed...

You may have noticed that I am not a big fan of Python or her cryptic error messages so I hope that you just say "AHA" and fix the thingy ;)

I don't think that the waypoints file is the problem since I tried various that worked before so I omit it here.

P.S.:
While I am here let me first thank you for your work on this.

Second, I have created a kind of "front end" in PHP: https://github.com/elkuku/Frox which I use only on my machine to manage my own portal list.

And another thing in JS here; https://github.com/elkuku/maptest with a (working) demo here: https://elkuku.github.io/maptest/
The thing here is to convert the whole maxfield plan (the "farm keys" list and the "links" list) to a GPX file (which is done by the PHP script above) and then display it on a map with your actual location. To be used when executing the maxfield out in the field.
This could also be loaded into a navigator so you can at least navigate to the portals when playing in unknown areas ;) (not tested)

So, thanks again for your hard work and I hope that you are still playing Ingress.

Had the same issue, downgrade ortools and install again:

Had the same issue, downgrade ortools and install again: sudo pip install ortools==8.2.8710

Wow that sounds like a plan :)
Unfortunally just copy and pasting the command gave me the following result:

$ sudo pip install ortools==8.2.8710
ERROR: Could not find a version that satisfies the requirement ortools==8.2.8710
ERROR: No matching distribution found for ortools==8.2.8710

OK let's investigate in Python land... ortools from google... the version you mention seems to be this one and looking at the assets, the version numer seems to be right, so... no typo...
let's find out the available versions... search the web, found a SO answer that tells me that there are actually five different ways to do this, depending on your pip version... for my version (21.0) teh command seems to be:
pip install --use-deprecated=legacy-resolver ortools==- sounds awesome...
The result was:

$ sudo pip install --use-deprecated=legacy-resolver ortools==
ERROR: Could not find a version that satisfies the requirement ortools== (from versions: 9.1.9490, 9.2.9972, 9.3.10459, 9.3.10497)
ERROR: No matching distribution found for ortools==

So it seems that the 8.2 version is no longer available for pip installation?
Is there any other way to downgrade this lib?

Thanks ;)

Hey all - sorry for the long delay in responding to this!

I am able to reproduce the error with ortools, and I have submitted an issue with them: google/or-tools#3202

I was able to run maxfield by installing an older version of ortools like @Sukhumi suggested.

@elkuku make sure you're using the latest pip:

:(

Anything else that I might update?

Maybe a local caching issue?.....

Hmmm... I wonder if this is a python version problem? I'm using 3.9 and you're using 3.10. Maybe ortools 8.x isn't supported in python 3.10 considering it doesn't show up in your pip index... Worth a shot trying 3.9 in a virtual environment and seeing what happens!

After an hour or so I have to confess, that this is not an easy task :(

Alright, it looks like the problem with ortools is a dependency issue with another package, protobuf.

google/or-tools#3202

Fix incoming...
