python setup.py install ignores install_requires

问题

I am unable to install the local packages using setup.py

Here is the project structure:

my-project/
  lib/
     local1/
        local1.1.0.whl
        index.html
     local2/
        local2.1.0.whl
        index.html
  setup.py

setup.py

import os

from setuptools import setup

setup(name='my project',
      version='1.0',
      description='my project',
      install_requires=[
        'lxml >= 4.3.0',
        'local1 @ file://localhost/{}/lib/local1/local1.1.0.whl'.format(os.getcwd()),
        'local2 @ file://localhost/{}/lib/local2/local2.2.0.whl'.format(os.getcwd()),
      ]
      )

I can install if I put the dependencies in a requirements.txt file and use pip install -r requirements.txt --extra-index-url lib/, but I want to know why is it not possible to do python setup.py install or if I am missing something.

This is the error that I get -

No local packages or working download links found for local2@ file://localhost//Users/anusha/Documents/my-project/lib/local2/local2.1.0.whl
error: Could not find suitable distribution for Requirement.parse('local2@ file://localhost//Users/anusha/Documents/my-project/lib/local2/local2.1.0.whl')

On searching, I found this issue on github, but does not give me any pointers or solution as to how it worked.

Any help is welcome, thanks in advance!

Note this comment from pganssle in the discussion "Setuptools install fails with PEP508 URLs" in setuptools's issue tracker:

Our policy to date has been that if using pip install fixes your problem, you should use pip install and we won't fix the issue.

I believe this is in line with the current evolution of the packaging tools and techniques in the Python community. So if your setuptools-based project with this requirement notation can be installed via pip install . and pip install --editable ., then look no further.
