pip unable to install because of missing ssl module

[metulburr]

im trying to install pandas on python3.6. It seems to work fine in python2.x.

Output:
metulburr@ubuntu:~$ sudo pip3 install pandas

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
