not installable via setuptools

Hi,

Attempting to package this on my Guix System, I get:

There doesn't appear to be any VERSION file packaged in the sdist archive.

Guix is very different from most being an immutable build system. NixOS is similar. My understand of NixOS is that you are required to install python packages via the Nix Packaging system. Does Guix differ when related to Python package installation?

Could you provide more information on what commands you used to issued during installation. Was it pip install scrape-schema-recipe?

Guix is one of the few OSes that I feels really different to use.

It works when installed via pip and conda (on my Linux Mint box):

In [1]: import scrape_schema_recipe

In [2]: scrape_schema_recipe.__version__
Out[2]: '0.2.0'

The VERSION file appears in the wheel file on PyPA. It is in the tar.gz file. Does it work when you install via pip from the repo?

$ pip install https://github.com/micahcochran/scrape-schema-recipe.git

Hi,

I don't think the Guix specifics are at play here; the problem is resolved when building scrape-schema-recipe fetching its sources from Git instead of from its PyPI sdist archive.

As I hinted in the original message, I believe the problem is that the sdist source archive is lacking a VERSION file, which is required by the setuptools build system (python setup.py build).

I hope this clarifies the problem. Thanks.
