我在装有MAMP（PHP7.2.10和MySQL 5.7.23 InnoDB）的Mac上安装了MediaWiki。没有错误发生，除搜索外所有内容均有效。它显示以下错误而不是结果：
[c1af9047a60a292a781befdd] /mediawiki/index.php?search=test&title=Spezial%3ASuche&go=Seite Wikimedia\Rdbms\DBQueryError from line 1457 of /Users/xxx/www/mediawiki/includes/libs/rdbms/database/Database.php: A database query error has occurred. Did you forget to run your application's database schema updater after upgrading?

第一个尝试是启动Web更新程序，但是/ mwconfig /仅允许下载LocalSettings.php。无法实际启动它。
有什么想法吗？谢谢！

我认为这与MySQL安装有关。重新安装服务器将其修复。
