Pip or whatever should be smart enough to use the latest available on python 2. Is that pr really necessary? Any details on what kind of error it solves?

Thanks for your reply.

When I installed requirements in my project yesterday, I got this error.

  ----------------------------------------

So，maybe that pr is helpful.( I'm not so sure, but it really solved this error. )

python and pip version:

Python 2.7.16
pip 19.1.1

Looks like you use a broken pypi mirror that don't have python_requires metadata? http://pypi.douban.com - what is that?!

vimiix commented 4 years ago

http://pypi.douban.com - what is that?!

It is a pypi mirror site for instead pypi.python.org in China. ╮(╯_╰)╭

I saw same question in setuptools issue tab.

ionelmc commented 4 years ago

Ooof. Can't you workaround this by pinning setuptools in your requirements? Having lazy-object-proxy have an upper constraint because some mirror is broken seems wrong. The problem doesn't reproduce without that mirror.

Got it, thanks.
