`azdev setup` fails to call `python` executable from conda environment on win32

Comienza en azdev/utilities/command.py, en la función py_cmd, e inspecciona cómo se selecciona el ejecutable de Python en win32. Reproduce azdev setup desde un entorno conda activado y verifica después que la instalación del paquete invoque el ejecutable de Python funcional del entorno en lugar de la ruta Scripts/python no válida.

When running azdev setup from within a conda environment on win32, the py_cmd function in azdev/utilities/command.py attempts to run Scripts/python from within the current conda env, rather than the python executable in the root of the environment:

(base) PS> conda activate az-dev
(az-dev) PS> azdev setup --cli <repopath> --repo <repopath>

Upgrading pip...
Command `C:\Users\<username>\AppData\Local\Continuum\anaconda3\envs\az-dev\Scripts\python -m pip install --upgrade pip` failed with exit code 1:
'C:\Users\<username>\AppData\Local\Continuum\anaconda3\envs\az-dev\Scripts\python' is not recognized as an internal or external command,
operable program or batch file.

As a workaround, modifying py_cmd to call sys.executable rather than using env_path seems to work:

def py_cmd(command, message=False, show_stderr=True, raise_error=False, is_module=True, **kwargs):
    """ Run a script or command with Python.
    :param command: The arguments to run python with.
    :param message: A custom message to display, or True (bool) to use a default.
    :param show_stderr: On error, display the contents of STDERR.
    :param raise_error: On error, raise CommandError.
    :param is_module: Run a Python module as a script with -m.
    :param kwargs: Any kwargs supported by subprocess.Popen
    :returns: CommandResultItem object.
    """
    from azdev.utilities import get_env_path
    env_path = get_env_path()
    python_bin = sys.executable
    if is_module:
        command = '{} -m {}'.format(python_bin, command)
    else:
        command = '{} {}'.format(python_bin, command)
    return cmd(command, message, show_stderr, raise_error, **kwargs)
