I'm modifying faker in anticipation to an open PR I have open with validators, and I want to be able to test the new dependency i will have.
setup(
name='Faker',
...
install_requires=[
"python-dateutil>=2.4",
"six>=1.10",
"text-unidecode==1.2",
],
tests_require=[
"validators@https://github.com/kingbuzzman/validators/archive/0.13.0.tar.gz#egg=validators-0.13.0", # TODO: this will change # noqa
"ukpostcodeparser>=1.1.1",
...
],
...
)
python setup.py test refuses to install the 0.13.0 version.
If I move the trouble line up to install_requires=[..] (which SHOULD not be there)
setup(
name='Faker',
...
install_requires=[
"python-dateutil>=2.4",
"six>=1.10",
"text-unidecode==1.2",
"validators@https://github.com/kingbuzzman/validators/archive/0.13.0.tar.gz#egg=validators-0.13.0", # TODO: this will change # noqa
],
tests_require=[
"ukpostcodeparser>=1.1.1",
...
],
...
)
pip install -e . everything works great -- the correct version gets installed.python setup.py develop same issue.My guess is setuptools/distutils doing something weird -- pip seems to address the issue. My question: how do I fix this?
Problematic code and references can be found here:
Easiest way to see the issue at hand:
docker run -it --rm python:3.7 bash -c "git clone https://github.com/kingbuzzman/faker.git; cd faker; pip install -e .; python setup.py test"
UPDATE: Since this has been fixed, the issue wont be replicated anymore -- all tests will pass

py:34: SetuptoolsDeprecationWarning: setup.py install is deprecated. Use build and pip and other standards-based tools. I found a very detailed write-up explaining this issue: "Why you shouldn't invoke setup.py directly" (October 2021).
install_requires is a section within the setup.py file in which you need to input a list of the minimum dependencies needed for a project to run correctly on the target operating system (such as ubuntu). When pip runs setup.py, it will install all of the dependencies listed in install_requires.
If you use setup.py , you have to visit the library's website, figure out where to download it, extract the file, run setup.py ... In contrast, pip will automatically search the Python Package Index (PyPi) to see if the package exists there, and will automatically download, extract, and install the package for you.
As a first step, pip needs to get metadata about a package (name, version, dependencies, and more). It collects this by calling setup.py egg_info . The egg_info command generates the metadata for the package, which pip can then consume and proceed to gather all the dependencies of the package.
Unfortunately, neither setup_requires nor tests_require support URL-based lookup or environment markers from PEP 508 yet. You need to use dependency_links, for example
setup(
...
tests_require=["validators>=0.13.0"],
dependency_links=['git+https://github.com/kingbuzzman/validators@master#egg=validators-0.13.0'],
)
