Azure DevOps AzureFunctionApp@1 not installing python dependencies-CodePudding

Using the Azure Devops task with current setup :

 task: AzureFunctionApp@1
  displayName: Deploy Lab
  inputs:
    azureSubscription: 'serviceConnection'
    appType: 'functionAppLinux'
    appName: 'myAwesomeApp'
    package: '.'
    runtimeStack: 'PYTHON|3.8'

Also, in the root directory (ie . in the ado task), I have a requirements.txt file that contains numpy

The deployment runs successfully but when I test the app, I have the following error:

Failure Exception: ModuleNotFoundError: No module named 'numpy'

Which simply means that the requirements.txt file is not considered or pip install -r requirements.txt didn't run successfully in the remote compute, what am I doing wrong ?

EDIT: Added a step to install the packages locally did work, but as numpy is a C built library it's dependent on the host machine and that doesn't work in the remote function app :lol:

The step that I added is this one:

- bash: pip install -r requirements.txt --target="./.python_packages/lib/site-packages"
  displayName: 'Install dependencies'

And the error:

Result: Failure Exception: ImportError: IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE! Importing the numpy C-extensions failed. This error can happen for many reasons, often due to issues with your setup or how NumPy was installed. We have compiled some common reasons and troubleshooting tips at: https://numpy.org/devdocs/user/troubleshooting-importerror.html Please note and check the following: * The Python version is: Python3.9 from "/usr/local/bin/python" * The NumPy version is: "1.22.3" and make sure that they are the versions you expect. Please carefully study the documentation linked above for further help. Original error was: No module named 'numpy.core._multiarray_umath' .

CodePudding user response：

Maybe you will have to use python 3.9 and the latest ubuntu agent in the pipeline
