I have installed Laravel 5 successfully and changed MySQL credentials in database.php file in config directory to \'
mysql\' => [ \'driver\'
I spent hours on this :-( and finally, it was really easy to hack
BEFORE
DB_PASSWORD=#Root2020$
UPDATED
DB_PASSWORD="#Root2020$"
I think the problem was # in the password, that's why I had to write my password into quotation marks.
