Re: PuLP Installation Problem

[Franco Peschiera]

Hello Nathan,

Could you please provide the way you’re installing PuLP in your python environment?
Try something like the following:

pip install pulp

We do automatic tests with Ubuntu and python 3.8 and they pass. Do you know if PuLP installs correctly in python 3.8?

Also, are you sure the problem is installing PuLP though? Because from what I can see in your error the problem seems to be installing with setuptools>=42, which is not a requisite for PuLP.

To Whom It May Concern:

First off, I would like to say that I have used PuLP in the past, and I absolutely love it. I think it's a fantastic package!

Unfortunately, I am now experiencing problems with PuLP. I have recently upgraded to Python 3.8.5 on my Mac, and whenever I try to install PuLP, I get an error message. Here is a snippet of what I receive:

  ERROR: Command errored out with exit status 1:
   command: /usr/local/opt/python@3.8/bin/python3.8 /usr/local/lib/python3.8/site-packages/pip install --ignore-installed --no-user --prefix /private/var/folders/sh/5_w_syfn1zz5ft34hdxchsmc0000gn/T/pip-build-env-p90w2a1z/overlay --no-warn-script-location --no-binary :none: --only-binary :none: -i https://pypi.org/simple -- 'setuptools>=42' wheel 'setuptools_scm[toml]>=3.4'

I used to have Python 3.7.5, and I was able to install and utilize PuLP without any errors. I only started experiencing this issue when I upgraded Python. I am hoping to get this problem as soon as possible because I will need to employ PuLP for my upcoming graduate class. 

Would someone be able to please help me with this? Any assistance you can provide would be greatly appreciated. Please let me know if you would like me to provide additional information. Thank you in advance for your help and have a great week!

Sincerely,
