ModuleNotFoundError: No module named 'azure'

I’m trying to run a web scraper via an Azure Function. When I run the function locally, it works no problem. But when I deploy the function to Azure I encounter a couple of ModuleNotFoundError Exceptions even though I’ve included both files in requirements.txt. I saw some other people ran into this issue, I tried the solutions in these posts but haven’t got anything to work.

Investigative information

• Function App name: scrapertest1
• Function name(s) (as appropriate): ScraperTest
• Core Tools version: 2.7.2254

Repro steps

Provide the steps required to reproduce the problem:

I use func azure functionapp publish scrapertest1 --build remote to deploy the app and monitor it from the live metrics stream.

Expected behavior

I expect the function to see the ‘azure’ and ‘bs4’ modules that work fine when I run the function locally.

Actual behavior

The function is deployed successfully but whenever my function tries to run it fails due to ModuleNotFoundError exceptions.

Known workarounds

I tried several different ways of deploying the function, all unsuccessful in getting around the issue: func azure functionapp publish scrapertest1 --build remote func azure functionapp publish scrapertest1 func azure functionapp publish scrapertest1 --build-native-deps --force

For me, there is a lot of confusion in docs about “How to deploy a Python Function in Linux Consumption Plan”. The docs are various in nature and tells a different story. From what I see, I am running from a deployment package . What it does is build everything and mounts it to /home/site/wwwroot/ folder. So what you gotta do is pack everything before you publish like this

pip3.7 install --target $(System.DefaultWorkingDirectory)/.python_packages/lib/site-packages -r requirements.txt

That resolved the "import requests " issue but I am still getting other import issues. I am using the template so that it could be different from you. Can you share your cli commands to publish?

@anirudhgarg I think I might have figured out the issue. Seems like the problem might have been related to the way I was calling my Python script from the __init__.py file. I’m importing the file like this now (as it says so in the docs): from . import my_file whereas before I was using the subprocess module. This seems to fix the issue for the bs4 package import error, I’ll see now if it resolves the other Azure import error
