The issue you're having is that you're not getting the wheel for some reason?

robert-cody · 2019-02-27T15:34:45Z

Try Python 3.7.

dbanty · 2019-02-27T15:35:24Z

I'm getting the same issue. It fails on Python 3.6 and 3.7 but succeeds on Python 2.7

alex · 2019-02-27T15:35:25Z

Yup, I can reproduce with python3. What the heck.

alex · 2019-02-27T15:38:25Z

Ok, what's happening is that we use abi3 wheels, so we only built a single wheel for all python3 versions. Except for some reason, our wheels aren't being built as abi3 now. We're investigating.

alex · 2019-02-27T15:38:48Z

We haven't changed https://github.com/pyca/cryptography/blob/master/.jenkins/Jenkinsfile-cryptography-wheel-builder in months, so I'm not sure what changed. If anyone understands this, we'd appreciate the assist.

robert-cody · 2019-02-27T15:41:17Z

BTW installation succeed with Python 3.4, but fails with 3.5/3.6/3.7.

alex · 2019-02-27T15:42:34Z

That makes sense, we use python3.4 as our "base" for the abi3 wheels, so we're ending up with normal python3 wheels, instead of abi3 ones.

alex · 2019-02-27T15:46:31Z

This seems to be a pip bug: pypa/pip#6304

Refs #4789, pypa/pip#6304

Ok, landing #4790 and rebuilding our wheels will resolve this. It'll probably be several hours before this is completed (blame it on timezones) -- I'd suggest pinning your cryptography dependencies until we release 2.6.1

2.6.1 fixes this.

@alex we're not getting the wheel with python 2.7 (tried 15 and 16) on Mac, getting this weird message but the Python requirement should be met:

Skipping link https://files.pythonhosted.org/packages/f5/2a/48848dd65908190d68ef389ad8ee9d0010278f7a9118f40d8fed7d84a326/cryptography-2.6.1-cp27-cp27m-macosx_10_6_intel.whl#sha256=6b9e0ae298ab20d371fc26e2129fd683cfc0cfde4d157c6341722de645146537 (from https://pypi.org/simple/cryptography/) (requires-python:>=2.7,!=3.0.*,!=3.1.*,!=3.2.*,!=3.3.*); it is not compatible with this Python

Any idea what this could be? Could cp27m vs cp27mu be the culprit? The latest version found is 1.8.2 and it is cryptography-1.8.2-cp27-cp27mu-macosx_10_10_x86_64.wh

@ludokx Your issue likely isn't related to the 2.6 problem we resolved. What do you get when you do python -c "import sys;print(sys.maxunicode)"? If the number is 1114111 you are running a wide unicode cp27mu build, which is odd since python.org, homebrew, and pyenv (except for a brief window 2 years ago) all ship cp27m builds.

We stopped shipping wide unicode wheels on macOS specifically because nobody uses them and maintaining that build infrastructure is non-trivial.

ludokx · 2019-03-15T03:25:02Z

@reaperhulk you're correct, that seems to be the culprit. I just checked with our folks and we pre-build our python (for reasons :)) and that changed recently. The change will be reverted so that we should be fine then. I'm also finally upgrading to 3.6 which works without any issue.

Thanks for looking into it!

anybody coming to this issue because trying to install twine 3.0.0 in a python 3.8 alpine 3.10 container fails with the exact issue listed above?

Dockerfile to reproduce the issue:

FROM python:alpine

RUN apk add build-base python3-dev libffi-dev
RUN pip install twine

Solution
Since last week it needs an additional dependency: libressl-dev
therefore, this works:

RUN apk add build-base python3-dev libffi-dev libressl-dev
