second step was to install it on openserver following the instructions:

$ php bin/console doctrine:query:sql "`cat database.sql`"
```

First, I went to the openservera console, through the commands I went to the project directory and typed $ composer install,
after which an error popped up:

Fatal error: Allowed memory size of 1610612736 bytes exhausted (tried to allocate 67108864 bytes) in phar://C:/OSPanel/modules/php/PHP-7.2-x64/composer.phar/src/Composer/DependencyResolver/Solver.php on line 223

Check https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors for more info on how to handle out of memory errors.

Next I went here my_project/web/config.php where the errors are displayed.

I tried to fix the first one, but nothing happened. After that, I decided to do everything from 0, just install the engine, went to the official Symphony website, downloaded the framework and installed it according to the instructions. I did it, but I still can't install this script ( https://azbukafree.com/skripty-php/doski-obyavleni...) . Help me if you can.
