ERROR: Package 'example_package' requires a different Python: 3.10.12 not in '>=3.12'

Question

I am trying to set up a package from a github repo. My default python in the conda environment is python 3.12. The pyproject.toml of the repo has the following lines:

[project]
name = "example_package"
version = "0.1"
requires-python = ">=3.12"
dependencies = [
    "numpy==1.26.4",
    "tqdm>=4.66.6",
    "pandas>=2.2.3",
    "submitit>=1.5.2",
]

[project.optional-dependencies]
dev = [
    "pre-commit>=4.0.1",
    "ipykernel>=6.29.5",
    "mypy>=1.13.0",
    "pytest>=8.3.3",
]

I try to install with command pip install -e .[dev]

And get the following error:

I don't understand this error. Seems like there is a version of example_package already installed and pip is trying to source that instead of referring to the pyproject.toml. How do I locate where example_package is stored and pip install the new version to my conda environment?
