Driver not found - "An exception occurred in driver: could not find driver" in Symfony 5

Question

I am currently facing this problem. I'm a real newbie when it comes to Symfony.

Question: When I create a new database using cli symfony console doctrine:database:create, I get the following error:

In AbstractPostgreSQLDriver.php line 102:

  An exception occurred in driver: could not find driver


In Exception.php line 18:

  could not find driver


In PDOConnection.php line 38:

  could not find driver

I am using php 7.4 with xampp, normally pdo_sql is installed:

extension=bz2
extension=curl
;extension=ffi
;extension=ftp
extension=fileinfo
extension=gd2
extension=gettext
;extension=gmp
;extension=intl
;extension=imap
;extension=ldap
extension=mbstring
extension=exif ; Must be after mbstring as it depends on it
extension=mysqli
;extension=oci8_12c ; Use with Oracle Database 12c Instant Client
;extension=odbc
extension=openssl
;extension=pdo_firebird
extension=pdo_mysql
;extension=pdo_oci
;extension=pdo_odbc
;extension=pdo_pgsql
extension=pdo_sqlite
;extension=pgsql
;extension=shmop

This is my .env file configuration:

###> doctrine/doctrine-bundle ###
# For the format, see https://www.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/configuration.html#connecting-using-a-url
# IMPORTANT: You must configure your server version here or in config/packages/doctrine.yaml
#
# DATABASE_URL="sqlite:///%kernel.project_dir%/var/data.db"
DATABASE_URL="mysql://root:@127.0.0.1:3306/dbname"
DATABASE_URL="postgresql://db_user:db_password@127.0.0.1:5432/db_name?serverVersion=13&charset=utf8"
###< doctrine/doctrine-bundle ###

This is my doctrine.yaml file configuration:

doctrine:
dbal:
    url: '%env(resolve:DATABASE_URL)%'
    # IMPORTANT: You must configure your server version here or in the DATABASE_URL environment variable (see .env file)
    #server_version: '13'
orm:
    auto_generate_proxy_classes: true
    naming_strategy: doctrine.orm.naming_strategy.underscore_number_aware
    auto_mapping: true
    mappings:
        App:
            is_bundle: false
            type: annotation
            dir: '%kernel.project_dir%/src/Entity'
            prefix: 'AppEntity'
            alias: App

I've been searching for hours but can't find any solution to my problem, does anyone have an idea? I'm using a Windows system.

Thank you very much!

Answer 1

If you are working on Linux, some extensions may be missing, run the following command

sudo apt-get install php-mysql php-pdo

Answer 2

If you want to use Mysql, please comment out this line of code: DATABASE_URL="postgresql://db_user:db_password@127.0.0.1:5432/db_name?serverVersion=13&charset=utf8" If not, comment out another line of code
