Download error on https://pypi.python.org/simple/setuptools_scm/: [SSL: CERTIFICATE_VERIFY_FAILED]

Environment

• pip version: 10.0.1
• Python version: 2.7 & 3.6.5
• OS: Windows 10 Pro, 1803, 17134.48

We have a requirements.txt file for pip to follow. Installation of setuptools_scm is what fails as it appears to be trying to download from the old domain - https://pypi.python.org/simple/setuptools_scm

I have tried installing pip manually via; curl https://bootstrap.pypa.io/get-pip.py -o C:\get-pip.py py -2 C:\get-pip.py py -3 C:\get-pip.py

Still fails.

Installing setuptools_scm manually via

py -2 -m pip install setuptools_scm

Works beautifully.

Expected behavior I expect setuptools_scm to install correctly through our requirements.txt . We have tried adding --extra-index-url https://pypi.org/simple to our command but same failure.

@DaMa-IT you can declare setuptools_scm as a build requirement in a pyproject.toml file, like so:

[build-system]
requires = [
    "setuptools",
    "wheel",
    "setuptools_scm",
]

This should work, provided one is using pip >= 10.

@RonnyPfannschmidt note that the README file on https://github.com/pypa/setuptools_scm still recommends the setup_requires approach. Maybe it should be changed, if the easy_install method is broken now.
