Issue While Creating Admin in Magento 2 CLI

I have been using Magento for a long time but after the Magento 2 launched, I am facing some technical issues, I am creating in Magento 2 CLI, following are the codes that I have already applied and trying to get it done successfully.

I have done with following:
Setup (Backup, Config)

Just having issue with Admin:

magento admin:user:create ‐‐admin‐user=“example” ‐‐admin‐password=“example123” ‐‐admin‐email=“” ‐‐admin‐firstname=“example” ‐‐admin‐lastname=“example”

Please help me to fix this issue.
