Thanks a lot to consider my issue.
I use yii2.0.
I tried many ways to fix the problem I met yesterday. And after I modified the function aferSave() in artkost/yii-qa/models/Answer.php and Question.php, it seemed to work. But unfortunately, I still did not install this extension successfully.Because when i use http://localhost/path/to/index.php?r=qa to access QA, there is an error page as follows:‍

can you help me to install this extension successfully?

You changed your configuration file?

'modules' => [
        'qa' => 'artkost\qa\Module',
        'userClass' => 'app\models\User',
        'userNameFormatter' => 'getUserName'
        ...
    ]

[F-12]

yes，I did chang my configuration file:
$config = [
'id' => 'basic',
'basePath' => dirname(DIR),
'bootstrap' => ['log'],
'modules' => [
'qa' => 'artkost\qa\Module',
'userClass' => 'app\models\User',
'userNameFormatter' => 'getUserName'
],
...
]

after doing this, I run the command
php yii migrate --migrationPath=@artkost/qa/migrations
error again like below:

How you install extension? through composer?
You can try another method
php yii migrate --migrationPath=@vendor/artkost/qa/migrations

Thank you so much!
With your help, I finally install the extension successfully.
