如何修复MediaWiki中Luasandbox扩展报错问题

环境与配置 #

• 托管服务器搭建MediaWiki 1.39站点
• 通过cPanel启用Scribunto扩展，LocalSettings.php中添加以下代码：

wfLoadExtension( 'Scribunto' );
$wgScribuntoDefaultEngine = 'luasandbox'; // Use LuaSandbox as the default engine

问题现象 #

创建模块页面并粘贴维基百科模块代码后，点击保存触发内部错误，错误信息如下：

[ZQkYSxr_nfXN6YUDbjbzjQAAkTM] /index.php?title=Module:For&action=submit Scribunto_LuaInterpreterNotFoundError: The luasandbox extension is not present, this engine cannot be used.
