**OS**
MacOS High Sierra 10.13.4

**python info**
Python 2.7.10
/usr/bin/python

**pip info**
Version : `pip 10.0.1 from /Library/Python/2.7/site-packages/pip (python 2.7)`
where:
```console
pip: aliased to noglob pip
/usr/local/bin/pip
```
Azure CLI was installed, not using `pip` but by `brew install` per the docs.
Azure version: **2.0.33** referencing python 3.6 (required) in the following location: `Python location '/usr/local/opt/python/bin/python3.6'`

Could install each of the **required** items passing the `--user` flag and resolve all but the azure-cli item.

No se nombra ningún archivo del proyecto, prueba ni punto de entrada. Empieza reproduciendo la instalación en macOS High Sierra con Python 2.7, pip 10.0.1 y Azure CLI 2.0.33; después, sigue las dependencias de instalación documentadas; se considera terminado cuando los paquetes requeridos se instalan sin errores de permisos ni una dependencia de azure-cli sin resolver.
