Why does an error occur when installing the demo version of Symphony 4?

Question

symfony

I'm trying to install a demo version of symphony on Windows, but I get
composer create-project symfony/symfony-demo
an error via composer: the requested PHP extension pdo_sqlite * is missing from your system.
I'm trying to install pdo_sqlite I get
composer require pdo_sqlite
an error that there is no such package, what am I doing wrong?

Answer 1

pdo_sqlite is a PHP module, not a framework. Installed depending on what system you have.
On debian-like Linux distributions via apt-get install pdo_sqlite.
