XF 2.3 Can't reinstall XenForo after deleting the database directly

[wangyu1314]

I'm doing a test to convert a vBulletin forum to xenforo, and I can't uninstall it due to a buggy component that exists in the xenforo database, after reinstalling xenforo, the buggy plugin still exists in the database, and there's no other way for me to do it, so I just deleted the mysql database corresponding to xenforo, and reinstalled it again! XenForo, it keeps reporting errors, what should I do?
Thank you.
