Packages no loading from Requirements.txt

Question

Packages no loading from Requirements.txt

Johnson, Jeremy 0

I have a simple Python app I am trying to deploy using a Function App. It was created using the "Develop in Portal" option, V1 programming model.

I uploaded the Requirements.txt file (since its not created when the function i created) and have the line with the package listed but I still get the following error:

Result: Failure Exception: ModuleNotFoundError: No module named 'requests'. Please check the requirements.txt file for the missing module

I've read all I could find and cant seem to get it to work. I don't use Python much, but we had this same app deployed a few years ago and it worked with no issues, I'm not sure what I'm missing. Any help would be greatly appreciated.

@Johnson, Jeremy Could you share details on how the deployment is done and which App Settings are in place?

I just create a function app in Azure, using the default settings. The init_.py is automatically created, I upload the requirements.txt file, and everything is edited in the Azure console.

@Johnson, Jeremy Were you able to resolve this issue based on the discussion with @Konstantinos Passadis below? In-portal development is for experiments and quick prototypes only. To avoid the type of issues that you're seeing, we recommend that you set up a local development environment along with configurations for the Deployment method and Build process that suits your needs. Feel free to get back to us if you need any assistance.

I believe I finally have it working (still running through some tests) thanks to @Konstantinos Passadis I had to uninstall and re-install VS Code (had an error there) and then run it as an administrator on my machine. I still get an Error: connect ECONNREFUSED error, but I can then still deploy it and get it to Azure. Not ideal, but at least it works once deployed.

Big thanks to @Konstantinos Passadis for all the help getting this going.

@Johnson, Jeremy Thanks for confirming, and glad to hear that you're making progress and have things working & running on Azure. Please consider marking one of the answers below as Accepted so that it may help others find the same info easily. The ECONNREFUSED error usually stems from the connection to the local server not being able to be established. So if you're now encountering different issues like this while setting up your local environment, feel free to make new posts and we'd be more than happy to continue to support you here on the MS Q&A channel.

Hello @Johnson, Jeremy

Welcome to Microsoft QnA!

I am confident that he code is not supported .The v1 means that your package shoul dupport python v3.6 which is not available anymore

Either in the TXT set the version of the package to an older one , or update the code to use newest Python Versions > 3.7 and on!

I hope this helps!

@Konstantinos Passadis

Thanks for the reply. I initially tried using V2 (and Python Version 3.11) however when I do there is no Requirements.txt created, and I cannot upload one without getting an error.

I just tried again to create one using V2, and now all the functions that were listed in the function app have disappeared.

Hello @Johnson, Jeremy!

Would you be able to send the Code ?

If it is not a problem please post it here !

Otherwise use v 3.7 and try with V1 again using a version on the package that is supported on 3.7

I hope this helps!

Since my old code was no longer available I tried starting from scratch with a new app, using 3.7. Because I'm having so many issues I've dummied the code down to just the following. This is my entire code.

import logging
import requests

from azure.functions import TimerRequest
from datetime import datetime, timezone


def main(mytimer: TimerRequest) -> None:
    utc_timestamp = datetime.utcnow().replace(tzinfo=timezone.utc).isoformat()

    if mytimer.past_due:
        logging.info('The timer is past due!')

    logging.info('Python timer trigger function ran at %s', utc_timestamp)

Requirements.txt looks like this

# DO NOT include azure-functions-worker in this file
# The Python Worker is managed by Azure Functions platform
# Manually managing azure-functions-worker may cause unexpected issues

requests

I get the following error User's image

Hello @Johnson, Jeremy!

Try requests==2.2.0

The issue points to requests not being installed

Maybe this specific setting will fix it

Please try and let us know !

I hope this helps!

@Konstantinos Passadis Really appreciate the help trying to figure out my issues.

I tried that and got the same error

Hello @Johnson, Jeremy!

Clear all lines from the TXT , make sure no line changes are there except the requests==x.x.x

Do not copy paste if possible

Leave the file name without caps . requirements.txt

Set the file to the root of the folder

Kindly let us know!

I hope this helps!

I tried starting over with V2 (and 3.11). It will not allow me to upload the requirements.txt file. It says it uploads successful then all I get is that error.

Are you using Consunption ?

Also

https://learn.microsoft.com/en-us/azure/azure-functions/functions-reference-python?pivots=python-mode-decorators&tabs=asgi%2Capplication-level#triggers-and-inputs

Both Python Functions programming models support local development in one of the following environments:

Python v2 programming model:

Visual Studio Code

Terminal or command prompt

Note that the Python v2 programming model is only supported in the 4.x functions runtime. For more information, see Azure Functions runtime versions overview.

Python v1 programming model:

Visual Studio Code

Terminal or command prompt

You can also create Python v1 functions in the Azure portal.

You have to adjust if you want to proceed V2

Also :

Python in-portal editing is only supported when running in the Consumption plan and using the Python v1 programming model.
In-portal editing is currently only supported for functions that were created or last modified in the portal. When you deploy code to a function app from outside the portal, you can no longer edit any of the code for that function app in the portal. In this case, just continue using local development. For compiled C# functions, Java functions, and other Python functions, you can create the function app in the portal, but you must also create the functions code project locally and then publish it to Azure.

I am using a consumption plan.

All my apps were created using the portal. I will see if I can get VS code connected to the site and get it working that way.
