我通过扩展 BladeCompiler 找到了解决方案。

<?php namespace Laravel\Enhanced;

use Illuminate\View\Compilers\BladeCompiler as LaravelBladeCompiler;

class BladeCompiler extends LaravelBladeCompiler {

    /**
     * Compile blade template with passing arguments.
     *
     * @param string $value HTML-code including blade
     * @param array $args Array of values used in blade
     * @return string
     */
    public function compileWiths($value, array $args = array())
    {
        $generated = parent::compileString($value);

        ob_start() and extract($args, EXTR_SKIP);

        // We'll include the view contents for parsing within a catcher
        // so we can avoid any WSOD errors. If an exception occurs we
        // will throw it out to the exception handler.
        try
        {
            eval('?>'.$generated);
        }

        // If we caught an exception, we'll silently flush the output
        // buffer so that no partially rendered views get thrown out
        // to the client and confuse the user with junk.
        catch (\Exception $e)
        {
            ob_get_clean(); throw $e;
        }

        $content = ob_get_clean();

        return $content;
    }

}
