Doctrine can't find the PostgreSQL PDO driver?

Question

I see this question is very similar but I have PDO and pdo_pgsql installed

• Why does Doctrine say it can't find the PDO driver?

Here is my error message:

 php app/console doctrine:mapping:convert yml ./src/Vendor/Bundle/MyBundle/Resources/config/doctrine/metadata/orm --from-database --force



  [PDOException]         
  could not find driver  



doctrine:mapping:convert [--filter="..."] [--force] [--from-database] [--extend[="..."]] [--num-spaces[="..."]] [--namespace[="..."]] [--em[="..."]] to-type dest-path 

Here is my config.yml settings

doctrine:
    dbal:
      connections:
        my_database:
          driver:   pdo_pgsql
          port:     5432
          dbname:   blah
          user:     foo
          password: bar
          charset:  UTF8

The host is configured in the prod and dev yaml files like this

doctrine:
    dbal:
      connections:
        my_database:
          host: localhost

running php -m on the command line I see that PDO, pdo_pgsql and pgsql are all installed

PDO
pdo_pgsql
pgsql

What am I missing?

Answer 1

Ugh..

You have to setup the default database first in the parameters.yml file

Well that's what worked for me

Answer 2

In Symfony 2.7 or more the problem is resolved by editing the app/config/config.yml file to leave it to the database which indicates the driver:

doctrine:
    dbal:
        driver: "%database_driver%"

This solution is also useful when multiple databases of different drivers are used, for example, a MySQL database , another PostgreSQL database, ...

Answer 3

First of all, verify your php.ini file: the extensions php_pdo_pgsql and php_pdo must be enabled. Make sure you apply this changes on php.ini file that your symfony project is using (I imagine you are using the tool app/console from symfony), check this on localhost/path_to_your_project/web/config.php . You know if this extensions are enabled executing the function phpinfo().

This command is also helpfull: php -m. It lists on console all the php modules that are loaded.

Tip: check out you Apache error log , there could be something wrong with the load of your extensions. This file is located according to your server configuration.
