Answer 1

Change "DB_HOST" in the .env file from "localhost" to "127.0.0.1"

I had the exact same problem. None of the above solutions worked for me. I solved the problem by changing the "host" in the /app/config/database.php file from "localhost" to "127.0.0.1" .

Answer 2

Can you run php artisan config:clear and restart the server

Answer 3

try to update XAMPP or whatever server using and with the latest PHP version.

I got the same error when I shifting my project to mac I tried everything at last I uninstall the XAMPP and install the XAMPP with the latest PHP version updated version.

I hope that helps.

Answer 4

Open the .env file and change it DB_HOST=localhost to DB_HOST=127.0.0.1

• DB_USERNAME should be set to root if you do not have a default username in the installation time.
• DB_PASSWORD If no password is set on the database, just clear it

After .env edit, must be clear cache: php artisan config:cache

Answer 5

In my case, changing the DB_HOST to localhost didn't fix the issue. I had to change it to mysql which works fine
