laravel PDO::ATTR_STATEMENT_CLASS requires format array(classname, array(ctor_args)); the classname must be a string specifying an existing class

Question

i was working on a laravel project then i installed a new package using composer and i found this error

PDO::ATTR_STATEMENT_CLASS requires format array(classname, array(ctor_args)); the classname must be a string specifying an existing class

i tried to :-

1. revert to previous commit on git
2. remove vendor folder and composer.lock and reinstall all with no results

Answer 1

Had the same problem here. Downgrading to composer require doctrine/dbal=2.6.3 did the trick so far.

Answer 2

I had same problem. After downgrading doctrine/dbal 2.7 to 2.6.*, the problem was resolved.
