                'pluginOptions' => [
                    'aSep' => ' ',
                    'mDec' => 0
                ]
            ]);?>

Answer 1

It looks like extead/yii2-autonumeric requires yiisoft\yii-bootstrap extension which uses Bootstrap 3.

You can install missing extension through composer:

composer require --prefer-dist yiisoft/yii2-bootstrap

Or you can add it in your composer.json and then run composer update to install it.

Edit: actually, I've missed that yii2-bootstrap4 and yii2-bootstrap5 extensions uses different namespaces so for yii2-autonumeric extension to work you have to install bootstrap 3 extension. If you can't use bootstrap 3, you should probably switch to another extension for formating values in inputs. For example kartik-v/yii2-number allows you to set what version of bootstrap should be used.
