How Can I import Psycopg2 into a lambda Function on AWS??? I have tried everything and It continues to Fail


I am trying to import the Psycopg2 library into a lambda function but everytime it continues to fail, I have tried pip installing the library then zipping it with the .py file, it fails… with “”Unable to import module ‘lambda_function’: No module named ‘psycopg2._psycopg'”. Then I tried to use Docker and create a container to identical to the runtime of lambda, and it failed with the same error msg, I even tried to create my own Layer and it still continues to fail, here is the Code for importing and getting a connection (which it never makes it too):

And I also tried with Psycopg-Binary which should counter any compatability issues with the lambda runtime but it still failes

import sys
import psycopg2
import boto3
import json
import os

try:
connection = psycopg2.connect(host = os.environ\["host"\],
user= os.environ\["username"\],
password = os.environ\["password"\],
dbname = os.environ\["dbname"\],
port = os.environ\["port"\])

# except psycopg2.Error as e:

    print(f"Connection Attempt Failed, error: {e}")

Things I have tried:

  • Tried zipping the .py file and the libraries
  • Tried Docker and getting the right versions of everything.
  • Tried using Psycopg-binary
  • Tried making and using a layer with Psycopg2
  • Tried using an already community built layer for psyocpg2

Did all of these things, and it still does not work,

Any help appreciated, ty.
