Issue in connecting Postgresql database through laravel

I am having a hard time setting up laravel 5.3 (running on wamp/windows) with pgsql. I am getting an error "PDO Exception - Could not find driver" when I am trying to migrate tables with "php artisan migrate"

  1. I installed postgres 9.6.
  2. I enabled the php extensions for postgresql:

enter image description here 3. I added postgres libraries to environment path variable

  1. I tested the pdo postgres connection with php and I am getting connected:


    $dbh = new PDO("pgsql:dbname=rotocms;host=127.0.0.1", "postgres", "mypassword");

    if($dbh){
     echo "connected";
    }else{
     echo 'there has been an error connecting';
    }

So I am stuck, cant get the migration to work in laravel. My .env:


    DB_CONNECTION=pgsql
    DB_HOST=127.0.0.1
    DB_PORT=5432
    DB_DATABASE=mydatabasename
    DB_USERNAME=postgres
    DB_PASSWORD=password

Here is the laravel error stack:

Also PostgreSQL (libpq) Version in the phpinfo() is 9.4.4 even though i installed PostgreSQL 9.6 not sure if that is ok..

Make sure you've uncommented the line that tells php where the Postgres driver is (usually extension=pgsql.so) in the main php.ini file, take a look at this - stackoverflow.com/questions/10085039/… – Saumya Rastogi
I am on windows and I posted my phpinfo postgresql part. the lines in my php.ini are uncommented: extension=php_pdo_pgsql.dll extension=php_pgsql.dll – Adnan Mujkanovic
Have you write database name user password in both .env and database.php file – Wasiq Muhammad
yes i tried that, restarted everything but still not working. still same error. :( – Adnan Mujkanovic

Under config\database.php it is a file name database.php

Here Select default to pgsql like this

'default' => env('DB_CONNECTION', 'pgsql')

Here modify this with all your details

'pgsql' => [
            'driver' => 'pgsql',
            'host' => env('DB_HOST', 'localhost'),
            'port' => env('DB_PORT', '5432'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'charset' => 'utf8',
            'prefix' => '',
            'schema' => 'public',
            'sslmode' => 'prefer',
        ]

Restart your server hopefully it connects

You have to look for a couple of things,

Make sure to configure the 'default' key in app/config/database.php

For postgres, this would be 'default' => 'pgsql',

Check if you have the correct PHP extensions installed. You need pdo_pgsql.so and pgsql.so installed and enabled. Instructions on how to do this vary between operating systems.

Uncomment the lines extension=pdo_pgsql.so and extension=pgsql.so in php.ini

Now copy libpq.dll from C:\wamp\bin\php\php5.*\ into C:\wamp\bin\apache*\bin and restart all services.

If the issue persists the look into your Environment Variables.

Let me know the results.

You also have to install the postgres driver locally. On macOS you can use brew.

Depending on your PHP version (try php -v in terminal), use below command:

brew install php71-pdo-pgsql
brew install php70-pdo-pgsql
brew install php55-pdo-pgsql

Also, if you are runninng Valet, make sure to do valet restart afterwards.
