**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.

Aucun fichier de projet, test ou point d’entrée n’est nommé. Commencez par reproduire l’installation sur macOS High Sierra avec Python 2.7, pip 10.0.1 et Azure CLI 2.0.33, puis suivez les dépendances d’installation documentées ; le travail est terminé lorsque les packages requis s’installent sans erreurs d’autorisation ni dépendance azure-cli non résolue.
