setuptools: setuptools 42.0.0 breaks with allow-hosts set globally

There are also configurations setting allow_hosts = None to prevent automatic download of dependencies altogether. It looks as though this use case is also broken.

Indeed, this is our use case as well.

Also note that the pip docs still include this approach for this use case, see https://pip.pypa.io/en/stable/reference/pip_install/#controlling-setup-requires

To have the dependency located from a local directory and not crawl PyPI, add this:

[easy_install]
allow_hosts = ''
find_links = file:///path/to/local/archives/

Anyway, for this use case (hard-failing if setuptools tries to access PyPI), this still works:

[easy_install]
index_url = ''
find_links = ''
