Strange "TransportError" after updating googlemaps python package

Question

I had installed a version of the googlemaps package for python 2.7 and it was perfectly working. After updating the package when I try to run the same code I get the message

TransportError: [('system library', 'fopen', 'No such file or directory'),
 ('BIO routines', 'BIO_new_file', 'no such file'), 
('x509 certificate routines', 'X509_load_cert_crl_file', 'system lib')]

and I don't have a clue of what it may be. I tried to roll back to a previous version of the package but the error still remains. The code I am trying to run is a very standard piece of reverse geocoding, something like:

import googlemaps

gmaps = googlemaps.Client(key="my_key_here")

reverse_result = gmaps.reverse_geocode((lat,lon))

for result in reverse_result:
    print(result["types"], result["formatted_address"])

Do you have any suggestions?

I solved simply by uninstalling/reinstalling the package, but I'd love to know what was and what caused the error.
