Setup Issue (setuptools-scm was unable to detect version for)

[103-5]

I follow the instruction in the README and all steps are completed except
pip install -e . , it results in lots of errors (see below).
It seems that setup.py needs to be modified due to

LookupError: setuptools-scm was unable to detect version for /root.

I've tried the solution (as following) in pypa/setuptools-scm#536 but it doesn't work
use_scm_version={"root": "..", "relative_to": __file__, "version_scheme": "no-guess-dev"},

Here is the errors:

Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.
For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj

note: This error originates from a subprocess, and is likely not a problem with pip.

Hi @103-5 , thanks for raising an issue! I am not an expert with setup-tools, but it might be a problem with how you've downloaded the code. Are you downloading via a ZIP file or using Git to clone the repo to your machine?

Hi @mattmcdermott, thanks for your attention. I downloaded the ZIP file and unzipped it to the root folder.

The good news is I was able to recreate your error by downloading the ZIP folder; I hadn't noticed this problem because I always install via git clone https://github.com/GENESIS-EFRC/reaction-network.git.

Since this seems more like a pip metadata issue, I would suggest one of these two options:

1. install a non-editable version of the code by doing pip install reaction-network (this will download and install from PyPI)
2. Install an editable version of the code by using the git clone command above and then the usual pip install -e . from within the directory.

If you are not doing any development on the code, then Option 1 should be very straightforward -- just make sure if you're running stuff with networks to install the additional graph-tool dependency as is specified in the README instructions.

Thanks for your help. Both of these two options works! The downloaded zip lacks .git folder compared to git clone one, and it might be the reason why the pip metadata issue exists.

That's great to hear you got it working! I'll make a note in the README instructions in a future PR.
