No module named azure in pyvenv

Description

Installing azure-cli to a Python 3 venv produces invalid az command.

$ python3.6 -m venv ~/azure
$ ~/azure/bin/pip install -q azure-cli
$ ~/azure/bin/python --version        
Python 3.6.1
$ ~/azure/bin/az
/usr/local/opt/python/bin/python2.7: No module named azure

Whatever magic the az script is attempting to do is apparently not detecting the virtual environment and is instead invoking an old Python from a different environment where azure is not installed.

It’s possible this installation method isn’t supported, but as a Python engineer, I would have expected it to work.

Using /usr/bin/env python doesn’t work either. Replacing it with $DIR/python does work, however:

$ sed -i -e 's|python |$DIR/python |' /opt/azure-env/bin/az
$ /opt/azure-env/bin/az --version | head -n 1
azure-cli (2.0.10)

I have both python and python3 environments installed. Chose toinstall azure-cli to python3. Even if you have alias pointing python to python3 did not help. The command $ cat $(which az) @derekbekoe pointed out solved the issue. In my case I edit the az file as simply changing the python in the last line to python3:

#!/bin/bash

SOURCE="${BASH_SOURCE[0]}"
while [ -h "$SOURCE" ]; do # resolve $SOURCE until the file is no longer a symlink
  DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"
  SOURCE="$(readlink "$SOURCE")"
  [[ $SOURCE != /* ]] && SOURCE="$DIR/$SOURCE" # if $SOURCE was a relative symlink, we need to resolve it relative to the path where the symlink file was located
done
DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"

export PYTHONPATH="${DIR}/src:${PYTHONPATH}"

python3 -m azure.cli "$@"

python3 above will automatically point to /usr/bin/python3 and solved the issue.
