集成工作得很好。但当我试图将它与xgettext for template string集成时，我得到了一个致命的错误。有一个错误

致命错误：未捕获Twig_Error_Loader：无法找到模板"C：/MAMP/htdocs/view/site/block/contactform.html"（查看：C：\MAMP\htdocs/view/site）。HTDocs\组件\twig\Loader\Filesystem.php（150）：Twig_Loader_Filesystem-

这是我的代码：

class mainController {

  var $twig = null;
  public $configs;
  public $langlibrary;

  const DEFAULT_LANGUAGE = 'en';

  public function __construct() {
    $this->configs = Config::getConfigiration();
  }

  public function loadTwig() {

    require_once 'components/Twig/Autoloader.php';
    Twig_Autoloader::register();

    $tplDir = ROOT.'/views/site';
    $tmpDir = 'cache';
    $loader = new Twig_Loader_Filesystem($tplDir);

    $this->twig = new Twig_Environment($loader, array(
        'cache' => $tmpDir,
        'auto_reload' => true
    ));

    $this->twig->addExtension(new Twig_Extensions_Extension_I18n());

    // THE PROBLEM BEGINS WHEN ADD CODE BELOW FOR INETGRATION
    foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($tplDir), RecursiveIteratorIterator::LEAVES_ONLY) as $file)
    {
        // force compilation
        if ($file->isFile()) {
            $this->twig->loadTemplate(str_replace($tplDir.'/', '', $file));
        }
    }
