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

Question

I'm currently face to this problem. I am really new beginer at Symfony.
Problem :
When i create a new db with cli symfony console doctrine:database:create, i am getting these errors :
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
Iam using php 7.4 with xampp and normaly 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 config :
###> doctrine/doctrine-bundle ###
# Format described at https://www.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/configuration.html#connecting-using-a-url
# IMPORTANT: You MUST configure your server version, either 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 ###
And this is my doctrine.yaml file config :
doctrine:
dbal:
url: '%env(resolve:DATABASE_URL)%'
# IMPORTANT: You MUST configure your server version,
# either here or in the DATABASE_URL env var (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: 'App\Entity'
alias: App
I have been searching for hours but i cant get any solutions to solve my problem, someone has an idea ?
I'm on windows.
Thanks a lot !

Answer 1

If you want to use Mysql , comment this line DATABASE_URL="postgresql://db_user:db_password#127.0.0.1:5432/db_name?serverVersion=13&charset=utf8"
If not comment the other line

Answer 2

if you are working in Linux, probably some extensions are missing,run those command
sudo apt-get install php-mysql php-pdo

Answer 3

I had the same problem, PHP 7.4.29, xampp, windows.
For the purpose of installing Xdebug I upgraded my PHP version to 7.4.29 (previously 7.4.18), and I guess this errror occured since then. Database connexion worked before. I copied the extensions from the old php.ini to the new one and the error remained.
What resolved the problem : added this line :
extension_dir = "D:\programs\xampp\php\ext"
And activated these extensions :
extension=bz2
extension=curl
extension=fileinfo
extension=gd2
extension=gettext
extension=mbstring
extension=exif
extension=mysqli
extension=pdo_mysql
extension=pdo_sqlite

Answer 4

In my case, I got my .env.local file from a colleague and stupidly saved it without the leading dot, so Symfony was using the values from the .env file, which reads
DATABASE_URL="postgresql://symfony:ChangeMe#127.0.0.1:5432/app?serverVersion=13&charset=utf8" rather than the correct DATABASE_URL="mysql://foo:bar#127.0.0.1:3306/baz?serverVersion=mariadb-x.y.z" from .env.local.

Answer 5

I'm running Homestead/vagrant on windows and my problem was, I wasn't able to execute this command php bin/console doctrine:database:create on windows even though I opened a terminal as administrator
As seen on these 2 pictures I tried Cmder and Git bash and both of them failed, saying an execption occured in driver: could not find driver
I then solved it by SSH into my vagrant box vagrant ssh navigated to the working symfony folder and ran the command from there php bin/console doctrine:database:create and for some reason that worked !
I wish there was an easier way to debug this stuff, but I guess that's how it is working with Windows. Hope this can help someone out there

Answer 6

php.ini
copy path
find the file then open it
delete the ; in extension=mysqli

Answer 7

I also had this problem, just uncomment the DATABASE_URL that you have on your computer either (sqlite, mysql or postresql).

Answer 8

I had the same problem when I typed the following command:
symfony console make:user User
I solved the problem with the command:
php bin/console make:user User.
Wanting to create a user

Answer 9

step 1 => go to Xaamp control panel then click config of Apache
step 2 => click on PHP(php.ini).browse through the file. you can able to see these extensions.
extension=bz2
extension=curl
remove ; from ;extension=pdo_pgsql and save it and close file
step 3 => now come back to your project.click on .env file and comment this line:
DATABASE_URL="postgresql://symfony:ChangeMe#127.0.0.1:5432/app?serverVersion=13&charset=utf8"
this works!

Answer 10

I had the same problem, I am runing a Symofny application with docker.
When you add doctrine-bundle to your app, in Dockerfile will appear this lines what will install drivers for postgres.
You have to remove it and add this line, this will install drivers for mysql
RUN docker-php-ext-install pdo pdo_mysql
I hope that helps to someone.

Answer 11

Delete or comment from .env file the line:
DATABASE_URL="postgresql://db_user:db_password#127.0.0.1:5432/db_name?serverVersion=13&charset=utf8"

Answer 12

I had the same problem to solve the problem:
type php --ini to see the path to the file php.init
if you are on vscode do ctr + click on the path otherwise follow the path manually on your computer to the file php.init make sure your open php.init file with admin right !!
edit the file and uncomment extension=pdo_mysql
save and retry php bin/console doctrine:database:create
type php -m for check if your're in list pdo_mysql
here an illustration
