Phabricator says MySQL Native Driver Not Available, but it doesn't seem so


I installed phabricator into ubuntu 18.04 and it was OK.
After installation, I checked setup issues page(/config/issue/php.myqlnd/) and found “MySQL Native Driver Not Available” issue.

I checked by php -i and the output was like this:

$ php -i
PHP Version => 7.2.6

mysqlnd => enabled
Version => mysqlnd 5.0.12-dev - 20150407 - $Id: 38fea24f2847fa7519001be390c98ae0acafe387

Does this mean mysqlnd has been installed? If so, why phabricator said it hasn’t??
