i can't install the ibm_db python package in my azure function

Question

I'm trying to access a IBM DB2 instance from an azure function, but as soon as i add the ibm_db package to my requirement.txt and publish the function, when trying to install this package it gives me the error described below

ERROR: Command errored out with exit status 1:

  Please install python-devel or python3-devel as instructed in "https://github.com/ibmdb/python-ibmdb/blob/master/README.md#KnownIssues" and continue with the installation

The goal is to be capable to access DB2 regardless the language. I tried with node and .NET but they also have their own issues with this package (or i may have done something wrong)

Any idea how to to avoid this error?

Thanks!
