[Python 3.6.4/Windows] Problem with module installation and SSL

[didier31]

Hi everybody

I encounter a problem with pip. Some other guys, here had similar trouble but it was under Linux.

Here is what I obtain when attempting to install a module with pip:

python -m pip install ptvsd
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting ptvsd
Could not fetch URL https://pypi.python.org/simple/ptvsd/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping
Could not find a version that satisfies the requirement ptvsd (from versions: )
No matching distribution found for ptvsd

Remark :

import ssl; print(ssl.OPENSSL_VERSION)

OpenSSL 1.0.2k 26 Jan 2017
(This is what I obtain with this snippet)

Suggestions ?

Thanks a lot by advance
