using conda python to create pipenv adds both python_version and python_full_version to pipfile

Hello,

If I use a miniconda environment’s python for creating a pipenv environment, it adds BOTH, a python_version and python_full_version (e.g. 3.9 and 3.9.13) to the pipfile, and that throws an error.

System details:

I am using Ubuntu 22.04 via WSL. System python is: 3.10.6 Pip version is: 22.2.2 Pipenv installed via pip (outside of any environment): 2022.10.9 Conda version is: 22.9.0 All are the latest right now

Steps to reproduce the error:

(mlzoomcamp is a conda environment with python 3.9.13 (but I also used a conda env with python 3.10 and the same issue persisted))

(base) mona@Memoona-PC:~$ pipenv --python=/home/mona/miniconda3/envs/mlzoomcamp/bin/python
# runs fine, but when I install something:
(base) mona@Memoona-PC:~/extra$ pipenv install numpy

It installs numpy correctly, but then throws this error:

Adding numpy to Pipfile's [packages]...
✔ Installation Succeeded
Pipfile.lock not found, creating...

python_version: 'python_full_version' must not be present with 'python_version'

The pipenv file at this time looks like this:

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
numpy = "*"

[dev-packages]

[requires]
python_version = "3.9"
python_full_version = "3.9.13"

I looked at the pipfile before the install command, and it has already added the 2 versions as soon as the environment was created.

I did find a fix, to manually remove the python_version line from pipfile.

Also, if I use the system python to create an environment, this issue doesn’t happen, so this is most likely a conda issue. Do I have to manually remove the python_version each time from the pipfile?

Thanks @stewartmiles – I just pushed the buttons – new release is building now.

@jerempy can you please submit this patch upstream in Plette? https://github.com/sarugaku/plette/blob/master/src/plette/models/sections.py#L20

IMHO the rule should be oneof, but I am not familiar with Cerberus. To say for 100%.
