Parse error in pip: "'-e git+h'": Expected W:(abcd...)

I have a private python package, hidden. In that package, I'd like to use another private package of mine, zempy.

In hidden's requirements, there is a line

git+https://gitlab.com/group/[email protected]#egg=zempy

...which I've also tried writing as:

-e git+https://gitlab.com/group/[email protected]#egg=zempy

And I'm installing hidden with python3 -m pip install . or python3 -m pip install -e . (in hidden's main directory)

But I got an error:

error in hiddenco setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers; Parse error at "'-e git+h'": Expected W:(abcd...)

This seemed like working before. Suddenly it stopped working. Anyone has an idea? I have tried nearly everything in that requirements line. It's installing without that line. But I need zempy in hidden.

I have double checked install_requires parameter in setup. It is a list of string.

The setup.py in hidden:

"""Setuptools for hidden package."""
from glob import glob
from os.path import basename, splitext

import setuptools
from setuptools import setup


def readme():
    """Return readme as string."""
    with (open('README.md')) as f:
        return f.read()


def get_requirements():
    """
    Return requirements as list.

    package1==1.0.3
    package2==0.0.5
    """
    with open('requirements.txt') as f:
        return [line.replace('\n', '') for line in f.readlines()]


setup(
    name='hiddenco',
    long_description=readme(),
    packages=setuptools.find_packages('src'),
    package_dir={'': 'src'},
    install_requires=get_requirements(),
    py_modules=[splitext(basename(path))[0] for path in glob('src/*.py')],
    include_package_data=True,
    zip_safe=False,
    python_requires='>=3.6, !=3.9.*, !=3.10.*'
)

And the requirements.txt:

coloredlogs
pymongo >=3.7.2
fasttext==0.9.2
pytest >=6.1.2
pandas <=1.5.0
numpy >=1.16.1, <=1.19.5
-e git+https://gitlab.com/group/[email protected]#egg=zempy

Your get_requirements function needs to return just a list of package names and (optional) versions. install_requires merely documents which packages and versions are required; it does not support specifying where or how to obtain them.

A quick and dirty fix is to just discard the extra information you crammed in there.

def get_requirements():
    """
    Return requirements as list.

    package1==1.0.3
    package2==0.0.5
    """
    with open('requirements.txt') as f:
        packages = []
        for line in f:
            line = line.strip()
            # let's also ignore empty lines and comments
            if not line or line.startswith('#'):
                continue
            if 'https://' in line:
                tail = line.rsplit('/', 1)[1]
                tail = tail.split('#')[0]
                line = tail.replace('@', '==').replace('.git', '')
            packages.append(line)
    return packages

This pulls out .../[email protected] and converts it to zempy==0.4.7.
