Connexion: pathlib installed in python_version > 3.4

[chimeno]

Description

In a clean virtualenv with python 3.6.2.
pip install connexion (1.1.16)
pathlib 1.0.1 is installed.

Expected behaviour

pathlib shouldn't be installed with python version > 3.4

Related issue: #493

• python --version: 3.6.2
• pip show connexion | grep "^Version\:" : 1.1.16
• python -c "import setuptools;print(setuptools.__version__)": 36.6.0

Also, it seems that the pathlib is deprecated in favour of pathlib2 as:
https://pypi.python.org/pypi/pathlib/ (Attention section)

If you compare the requirements of 1.1.14 and 1.1.16 you can see a regression that installs pathlib and typing even if they are not required.

My guess is that the person who built the last connexion distribution had an old setuptools which discarded the extra python_version < "3.4".

@chimeno thanks for reporting this. Would you be interested in providing a fix in the form of a PR?

[chimeno]

Based on @NicolasLM , and If I'm not wrong, publishing a new release with a recent enough setuptools could fix the issue.

This should now be fixed with the latest 1.2 release (pathlib is no longer installed):

@chimeno can you check?

[NicolasLM]

I confirm that the release 1.2 fixes the issue.

[chimeno]

Confirmed!
