I had to reinstall 'openSuse Leap 15' because of a virus that I couldn't crush.
So, I'm faced with rebuilding my tool set.
I have reinstalled pyenv, (in home directory).
Now have to install python 3.7.0, using pyenv

It seems to be happy for a while, then runs into a problem on the build.
It can't find _ctypes in the library.
I thought I could go to github, find the module and manually add it, but that's not possible with this install method since it creates a new working tree in /tmp for each session.
Here's the details:

Output:
...:~> pyenv install 3.7.0

I was successful with the old linux, (same release I believe), but don't know how to fix, and can't remember having this issue before (which also had python 3.7.0)

Since I haven't been able to find an answer to this problem yet, I loaded python 3.6.6 as the default for pyenv. That will have to do for now.

I successfull build python 3.7.1 with pyenv on openSUSE Tumbleweed after installing
libffi-devel.

This post was from last September. I have since left OpenSuse, too many issues. Now back on Linux Mint. No issues whatsoever.
