[Python-modules-team] Bug#902710: bcrypt fails to import with python3.7: ModuleNotFoundError: No module named '_cffi_backend'

[Christoph Berg]

Package: python3-bcrypt
Version: 3.1.4-2
Severity: normal

Hi,

on unstable, with python3.7:

$ python3.7
Python 3.7.0 (default, Jun 27 2018, 14:40:03)
[GCC 8.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import bcrypt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/bcrypt/__init__.py", line 25, in <module>
    from bcrypt import _bcrypt
ModuleNotFoundError: No module named '_cffi_backend'

Spotted because it makes "import paramiko" fail.
