【问题讨论】：

你目前使用的是哪个 laravel 版本？

您使用的是哪个版本的 PHP？

这个错误是由于PHP版本造成的。你用的是哪个版本？

php版本为7.3.11

和你的 laravel 版本？

【参考方案1】：

此错误是由PHP 版本引起的。很可能是PHP 7.2 版本。见下文：

Document changes of PHP 7.2

解决这个问题：

将您的PHP 版本升级

或

修改1185的行 vendor\laravel\framework\src\Illuminate\Database\Eloquent\Builder.php文件

$originalWhereCount = count ($ query-> wheres);

到

$originalWhereCount = 0;
if (is_array ($ query-> wheres) || is_object ($ query-> wheres)) 
    $originalWhereCount = count ($ query-> wheres);
