Azure-docs: Unable to Verify Python Version

Created on 27 Jun 2019  Â·  5Comments  Â·  Source: MicrosoftDocs/azure-docs

Has anyone come across "unable to verify python version. Please make sure you have Python 3.6 installed" when following the doc at https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-first-function-python

When I try to publish the app, I get the error.
Python is installed and I've verified by py --version

C:\Users\azureAdmin>py --version
Python 3.6.8

@jcanose81 Python Functions run on Python virtual environment - based on the screenshot that you have provided, it doesn't look like you have activated one per this step.

Thank you for the feedback. I'm following the instructions to the T on the website, but one thing I've had to do is use PowerShell for everything. CMD or Bash won't accept my commands. Please see output below from PowerShell.

In the output below, am I still not activating a python virtual env?

Note: some errors in spelling on my part in "MyFunctionProj" and initial "py -3.6" command

In the step where I have to use Bash, that is where I am getting the python not installed error.

Thank you,

Windows PowerShell

Python is activating, but when I use git bash to enter "func azure functionapp publish " that's when I get the error that there is no valid python version.

It's when I try to publish the app that I get the python error from my initial post.

Edit - July 8th 2019
I found other documentation on creating an HTTPTrigger
The below worked perfectly.
https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-first-azure-function

I appreciate all the help and comments with this issue. Perhaps when I have more time I will re-visit the Python error and figure it out.
