Laravel: Error [PDOException]: Could not Find Driver in PostgreSQL

Php Database Postgresql Laravel Syntax Error

Php Problem Overview

I'm trying to connect with PostgreSQL database through Laravel in order to do a php artisan migrate but doesn't seem to be directed since it's reading the database name of MySQL.

Here are the commands from database.php:

'connections' => array(

	'sqlite' => array(
		'driver'   => 'sqlite',
		'database' => __DIR__.'/../database/production.sqlite',
		'prefix'   => '',
	),

	'mysql' => array(
		'driver'    => 'mysql',
		'host'      => 'localhost',
		'database'  => 'database',
		'username'  => 'root',
		'password'  => '',
		'charset'   => 'utf8',
		'collation' => 'utf8_unicode_ci',
		'prefix'    => '',
	),

	'pgsql' => array(
		'driver'   => 'pgsql',
		'host'     => 'localhost',
		'database' => 'postgres',
		'username' => 'postgres',
		'password' => 'root',
		'charset'  => 'utf8',
		'prefix'   => '',
		'schema'   => 'public',
	),

	'sqlsrv' => array(
		'driver'   => 'sqlsrv',
		'host'     => 'localhost',
		'database' => 'database',
		'username' => 'root',
		'password' => '',
		'prefix'   => '',
	),

),

If I remove the MySQL paths I'll get:

[InvalidArgumentException]
Database [mysql] not configured.

EDIT: When trying to do php artisan migrate I get a 'PDOException: could not find driver'. I'm using WAMP and I'm in Win8.1. Using PostgreSQL as database.

EDIT: Have experimented a series of alternative solutions but I'm still ought to get this solved. The php.ini file was checked in Apache, WAMP (from php folder) and PostgreSQL. The extension_dir is correct as it being -> extension_dir = "c:/wamp/bin/php/php5.5.12/ext/"

The extension=pdo_pgsql.dll and extension=pgsql.dll are uncommented.

Done the PATH trick in the 'System Variables' and rebooted. No chance.

Thanks for the help so far.

These are my drivers php_pdo_driver.h & php_pdo.h from C:\Program Files (x86)\PostgreSQL\EnterpriseDB-ApachePHP\php\SDK\include\ext\pdo

Solution 1 - Php

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

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

If you are receiving a [PDOException] could not find driver error, check to see 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.

For Windows, the pgsql extensions should come pre-downloaded with the official PHP distribution. Just edit your php.ini and uncomment the lines extension=pdo_pgsql.so and extension=pgsql.so

Also, in php.ini, make sure extension_dir is set to the proper directory. It should be a folder called extensions or ext or similar inside your PHP install directory.

Finally, copy libpq.dll from C:\wamp\bin\php\php5.*\ into C:\wamp\bin\apache*\bin and restart all services through the WampServer interface.

If you still get the exception, you may need to add the postgres \bin directory to your PATH:

System Properties -> Advanced tab -> Environment Variables
In 'System variables' group on lower half of window, scroll through and find the PATH entry.
Select it and click Edit
At the end of the existing entry, put the full path to your postgres bin directory. The bin folder should be located in the root of your postgres installation directory.
Restart any open command prompts, or to be certain, restart your computer.

This should hopefully resolve any problems. For more information see:

For PDOException: could not find driver for MySQL, and if it is Debian based OS,

sudo apt-get -y install php5-mysql

Solution 3 - Php

For PHP 7 in Ubuntu you can also do:

sudo apt-get install php7.0-pgsql

So, now you can do not uncomment lines in php.ini

UPD: I have a same error, so problem was not in driver. I changed my database.ini, but every time I saw an error. And I change database config in .env and errors gone.

Solution 4 - Php

This worked for me:

$ sudo apt-get install php-gd php-mysql

Solution 5 - Php

I realize this is an old question but I found it in a Google search so I'm going to go ahead and answer just in case someone else runs across this. I'm on a Mac and had the same issue, but solved it by using HomeBrew. Once you've got it installed, you can just run this command:

brew install php56-pdo-pgsql

And replace the 56 with whatever version of PHP you're using without the decimal point.

Solution 6 - Php

I had the same issue. This is what worked for me.

There are 2 php.ini files:

C:\wamp\bin\apache\apache2.4.9\bin
C:\wamp\bin\php\php5.5.12

NOTE: This is using my version of PHP and Apache, change to what yours are.

The php.ini file located in the both folders is what you need to update, the extentions:

extension=php_pdo_pgsql.dll
extension=php_pgsql.dll

These are what you need to uncomment (remove the ; symbol).

Restart both Wamp and the Command Prompt.

Hopefully it will work for you :).

Solution 7 - Php

sudo apt-get install php7.1-pgsql

Solution 8 - Php

I got this problem too. I have solved this issue already. If u are using Wamp then perform the following steps.

>1. Go to wamp64/www/bin/php/php* (where * is the php version you are using) 2. Edit file php and uncomment this line by removing the semicolon:

;extension=pdo_pgsql to extension=pdo_pgsql

> 3. Save and restart your Wamp server

If it does not work, please check your .env and config/database again.

Solution 9 - Php

I had the same error on PHP 7.3.7 docker with laravel:

This works for me

apt-get update && apt-get install -y libpq-dev && docker-php-ext-install pdo pgsql pdo_pgsql

This will install the pgsql and pdo_pgsql drivers.

Now run this command to uncomment the lines extension=pdo_pgsql.so and extension=pgsql.so from php.ini

sed -ri -e 's!;extension=pdo_pgsql!extension=pdo_pgsql!' $PHP_INI_DIR/php.ini

sed -ri -e 's!;extension=pgsql!extension=pgsql!' $PHP_INI_DIR/php.ini

Solution 10 - Php

The driver came disactivated by default you should active by yourself. after that it will work well.

I hope this do.

Solution 11 - Php

Solved after 3 hours... I am using WAMP (PHP 7.2.4), PostgreSQL 10, Laravel 5.6.29. Loaded PHP extensions (pgsql, pdo_pgsql) from Wampserver 3.3, then I was able to connect to the PostgreSQL server with a simple php testcode from the www directory. But $ php artisan migrate still returned

> PDOException::("could not find driver")

I checked the shell (git bash for windows) with $ php --ini, that returned C:\wamp64\bin\php\php7.2.4\php.ini instead of c:\wamp64\bin\apache\apache2.4.33\bin\php.ini, loaded by WAMP So you have to uncomment pgsql and pdo_pgsql extensions also in C:\wamp64\bin\php\php7.2.4\php.ini, and then migrate will work ...

Solution 12 - Php

In Linux(Ubuntu) just install the driver like so:

sudo apt-get install php-pgsql

This will install the driver with using your php current version.

Solution 13 - Php

For those wanting to use Postgresql on OpenSuse (and co), try the following:

zypper --no-refresh in php5-pgsql

Solution 14 - Php

In Windows 8 PC with Laragon 3.4.0 180809, I faced the same issue. It happened in my case because I updated Laragon and it added a new version of PHP. So in laragon/bin/php/ I actually had two directories:

php-7.1.20-Win32-VC14-x64
php-7.1.7-Win32-VC14-x64

I added 7.1.20 into my PATH variable. But in my Command Console, running php --ini was showing that the path actually was fetching from the older one: php-7.1.7-Win32-VC14-x64. So I deleted the old one (for safety, I put it in Recycle Bin). But Laragon failed to start after that.

So, in laragaon/etc/apache2/mod_php.conf, I changed the path to the latest PHP version. Then restarted Laragon and the issue is resolved. 

Solution 15 - Php

For Ubuntu like 20.04+ just install:

sudo apt install php-pgsql

Remember to install apache2 and php before. It'll put the drivers in the right path on installation.

Solution 16 - Php

Old thread I know, but I lost a couple of hours of my life with this. You also need to set the DB info in the .env file. You don't have to specify the driver here because the default specified in database.php is used (I think). I was struggling because it had DB_CONNECTION=mysql in the .env file and I was using pgsql.

Solution 17 - Php

Just run this command

sudo apt-get -y install php*-mysql

Solution 18 - Php

This worked for me:

$ sudo apt-get -y install php5.6-pgsql
$ sudo service apache2 restart

I am working with 32bit Ubuntu 14

Solution 19 - Php

I see you are using Windows. I was not able to fix this with enabling any of the extensions that come with my Windows WAMP Server. I tried PDO_ODBC and others and even found the Microsoft Official PDO_SQLSRV.

The solution for me was to install the PDO_SQLSRV drivers from a 3rd party website. I found the drivers through http://robsphp.blogspot.nl/2012/06/unofficial-microsoft-sql-server-driver.html

I usually don't use DLLs from random websites, but I was desperate and this worked for me. Hoping it might save others numerous hours of frustration.

Solution 20 - Php

Using Laravel V 5.5.39 with Php 7.1.12 is working fine, but later (newer) php versions cause the problem. So, change Php version and you will get the solution 100% .
