PSA,

Python 3.7's ssl module will not work on Ubuntu 14.04 any more. I'm going to push several patches soon that depend on OpenSSL 1.0.2 or 1.1.0 APIs. See https://mail.python.org/pipermail/python-dev/2018-January/151718.html

I got the following error when trying to install CPython git-master via pyenv:

The Python ssl extension was not compiled. Missing the OpenSSL lib?

(https://travis-ci.org/yan12125/python3-android/jobs/335168981)

I guess it's related to this issue? The CPython commit that requires OpenSSL 1.0.2+ is merged 3 days ago: python/cpython@61d478c

It's very likely. The ssl module in 3.7 no longer compiles with OpenSSL from Ubuntu 14.04.

Check your configure output. On a system with compatible libssl, it looks like this:

checking whether compiling and linking against OpenSSL works... yes
checking for X509_VERIFY_PARAM_set1_host in libssl... yes
checking for --with-ssl-default-suites... python

If the second line ends with no, then either OpenSSL is too old or you have LibreSSL.

@yan12125 You are using pyenv, so I believe the fix will come from that tool, not Travis.

Update test suite and travis to Python 3.7b1.

The build cache was the only thing keeping 3.7.0a4 around; it can no
longer be installed from pyenv. And I accidentaly deleted the master
build cache, so we have no choice.

It may be difficult to get 3.7b1 installed due to

travis-ci/docs-travis-ci-com#1710 adds a note to inform users that recent *-dev and nightly do not work.

So 3.7 is broken on Travis
91122bd 
Because they don't support OpenSSL's 1.0.2 or newer API.
See: travis-ci/travis-ci#9069

But, this will work locally with 3.7 - at least Python 3.7.0a2 (default, Oct 18 2017, 18:58:26)
The requirements.txt fix in the last update fixes a compatibility issue that websockets handled 3 months ago but didn't update in versioning.

As the simplest workaround, change the following in your .travis.yml:

This solved the issue for me.
See my example .travis.yml.

Note: switching to Xenial is important. While deadsnakes also include a python3.7 build for Trusty, that version doesn't include SSL support and we're back on Square 1.

Unfortunately I find "xenial" quite flaky. They relatively often fail to boot or find /var/lib/dpkg/lock locked by something else (but what?). Restarting build jobs helps.

The configuration to get Python 3.7 is:

language: python
sudo: required
dist: xenial
python: "3.7"

Adjust accordingly if your build requires multiple jobs.
