Etrange erreur SSL lors de l'insertion de la base de données via la ligne de commande

Question

J'ai un fichier (appelé conversation_template.py) que j'utilise pour amorcer ma base de données DynamoDB, et cela a fonctionné jusqu'à très récemment.

import boto3 

dynamodb = boto3.resource('dynamodb', region_name='us-east-1') 
table = dynamodb.Table('tablename') 

data = {'<data_goes_here>'} 


def add_to_table(): 
     table.put_item(Item=data) 


add_to_table() 

Maintenant, quand je le lance dans ma ligne de commande, je reçois ceci:

J'ai essayé de savoir où l'erreur vient, mais je ne pouvais pas le faire. Même les messages d'erreur ne m'ont pas amené nulle part.

Je reçois une erreur SSLError; le protocole est inconnu. J'ai trouvé que ce type d'erreur pourrait être lié à moi essayant de me connecter aux serveurs de proxy mais je n'utilise pas un et n'ai pas fait ainsi dans le passé non plus.

Des idées sur d'où cette erreur pourrait provenir?

Answer 1

Ce qui est travaillé à la fin est de quitter mon environnement virtuel en cours et lancez:

/Applications/Python\ 3.6/Install\ Certificates.command 

Et puis je suis entré dans mon environnement virtuel encore et couru:

pip install certifi 

qui a été fixé il.

J'ai reçu de l'aide d'un ami qui soupçonnait que cela pourrait concerner la vérification de certification (liée à ceci: urllib and "SSL: CERTIFICATE_VERIFY_FAILED" Error) mais je n'ai pas compris pourquoi je n'ai pas eu une erreur de "vérification de certificat échouée".
