Import pytz into AWS lambda function

问题

I'm writing a lambda function that works with datetimes and trying to import pytz so I can have timezone be accounted for when comparing.

import boto3
import pytz
from datetime import timedelta, date, datetime
from boto3.dynamodb.conditions import Key, Attr

causes this to display

{errorMessage=Unable to import module 'lambda_function'}

but when I remove import pytz the function fires (it just doesn't work properly without timezone info)

回答1:

You need to install the pytz package so it's available for your lambda. The way you do this is having pip install it into the directory you are going to zip and upload to AWS (i.e. peered with the file containing your lambda function).

pip install -t path/to/your/lambda pytz

Then when you zip it up and upload it, it will be available.

Editing to add that I created a tool to do a lot of this for you - you can find it here: https://github.com/jimjkelly/lambda-deploy

If you don't have access to pytz in your environment, maybe you have access to python-dateutil. In that case you can do:

import datetime
import dateutil.tz

eastern = dateutil.tz.gettz('US/Eastern')
datetime.datetime.now(tz=eastern)
