我正在将Eloquent与Slim Framework结合使用来构建一个小型API。由于某种原因,我收到此错误,我找不到问题:
Target [Illuminate\Contracts\Debug\ExceptionHandler] is not instantiable.
数据库设置正确。在服务器上的暂存环境中抛出此错误。在本地,使用MySQL 5.6.29,它可以很好地工作。虽然我不认为它与MySQL 5.7有关,因为我在同一台服务器上运行了另一个使用相同版本的Eloquent的应用程序。
有人能指出我正确的方向吗?
我正在使用:

我怀疑它与未注册的错误处理程序有关:
但是如何在不使用Laravel时注册自定义错误处理程序?
更新 @patricus的解决方案可以实现如下:
// bootstrap Eloquent ORM
$container = new Container();
$container->singleton(
'Illuminate\Contracts\Debug\ExceptionHandler'
, 'My\Custom\DatabaseExceptionHandler'
);
$factory = new ConnectionFactory( $container );
$connection = $factory->make([
'driver' => 'mysql'
, 'host' => App::config( 'database_host' )
, 'database' => App::config( 'database_name' )
, 'username' => App::config( 'database_user' )
, 'password' => App::config( 'database_password' )
, 'charset' => App::config( 'database_charset' )
, 'collation' => App::config( 'database_collate' )
, 'prefix' => ''
]);
$resolver = new ConnectionResolver();
$resolver->addConnection( 'default', $connection );
$resolver->setDefaultConnection( 'default' );
// initialize connection
Model::setConnectionResolver( $resolver );

您应该能够访问容器以通过胶囊注册您自己的异常处理程序。
$capsule = new \Illuminate\Database\Capsule\Manager();
$capsule->getContainer()->singleton(
\Illuminate\Contracts\Debug\ExceptionHandler::class,
\Your\ExceptionHandler\Implementation::class
);
如果你想要一个真正快速,非常愚蠢的异常处理程序,你可以使用它:
class DumbExceptionHandler implements \Illuminate\Contracts\Debug\ExceptionHandler
{
public function report(Exception $e)
{
//
}
public function render($request, Exception $e)
{
throw $e;
}
public function renderForConsole($output, Exception $e)
{
throw $e;
}
}
注意:未经测试。我相信这应该可以看到代码。

请确保您的xampp服务器和数据库服务器可以正常运行。
