[gdal-dev] GDAL version in pip requirements file

[Peter Schmitt]

I know you mention requirements.txt, but I write my setup.py with a
function that uses gdal-config to get Python bindings for the version of
GDAL I have installed.  It looks something like this:

from setuptools import setup, find_packages
from subprocess import check_output

class GdalNotFoundError(Exception): pass

def gdal_version():
    """Returns version provided by gdal-config

    >>> gdal_version()
    '3.3.1'
    """

    try:
        version = check_output(['gdal-config', '--version'])
    except FileNotFoundError as err:
        raise GdalNotFoundError('GDAL must be installed and `gdal-config`
must be in the $PATH to continue')

    return version.decode('utf-8').strip()

setup(
    name='foo',
    description='bar.',
    version='0.0.0',
    py_modules=['cli'],
    packages=find_packages(exclude=['tests', 'docs']),
    include_package_data=True,
    install_requires=[
        f'gdal=={gdal_version()}',
    ],
    entry_points='''
        [console_scripts]
        foo=cli:cli
        ''',
)
