pip install with ensurepip on PyPy3.5 v5.10 in Windows 7 x64

Question

Why I can't install pip with pypy3 -m ensurepip ? I have unpacked PyPy from official package , and followed instructions at official docs but resulting in an error. Interpreter log is below.

Traceback (most recent call last):

Answer 1

The errno module on pypy3 on Windows (which is beta) is indeed incomplete. This has been fixed after the 5.10.0 release and will be included in the 5.10.1 release.

Answer 2

We build nightly zip files off the latest HEAD, available here . It would be great if you could try out the latest windows version and let us know on IRC at #pypy, or on the pypy-dev mailing list, or by filing an issue on our bitbucket issue tracker whether it works for you, so that we will not need to do a 5.10.2 bug release fix after the current one.
