Conda build can not find dependencies

Hello, I am creating my first python package that I would like to publish on both pypi and conda-forge. I am able to sucessfully build, install and run the package a pip package from a local repository but I am and able to even build the conda package.

When building the conda package I am using the command:

conda build .

from the package directory. Conda build starts the build process then quits with the following error:

%SRC_DIR%>call “C:\ProgramData\anaconda3\condabin\conda.bat” activate “%PREFIX%”

  • Creating isolated environment: venv+pip…
  • Installing packages in isolated environment:
  • build
  • setuptools
    < ERROR: Could not find a version that satisfies the requirement setuptools
    (from versions: none)

I believe that these 2 packages are being pulled in because I have this listed in my pyproject.toml

[build-system]
requires = [
“setuptools”,
“build”
]

build-backend = “setuptools.build_meta”

I have both python-build and setuptools listed as build requirements in the meta.yml file so I would expect that both setuptools and python-build would be available in the build environment. Can some one please tell me what I am doing wrong. This is my first python package so I am probably doing something wrong.

I have the full source posted on github.
