Twig未在Silex中加载

Question

我正在尝试使用Silex FW运行应用程序。我有类似于示例中的源代码：

require_once __DIR__.'/silex.phar'; 

$app = new Silex\Application(); 

$app['debug'] = true;

$app->register(new Silex\Provider\TwigServiceProvider(), array(
    'twig.path' => __DIR__ . '/views',
    'twig.class_path' => __DIR__ . '/vendor/twig/lib',
));

$app->get('/hello/{name}', function ($name) use ($app) {
    return $app['twig']->render('hello.twig', array(
        'name' => $name,
    ));
}); 

$app->run(); 

但是我得到了这个错误：

Fatal error:  Class 'Twig_Environment' not found in phar:///var/www/silex/silex.phar/src/Silex/Provider/TwigServiceProvider.php on line 40

这个问题也是posted on GitHub的问题。

Answer 1

解决方案是使用Composer和autoload.php。

Answer 2

使用这种方法，您的twig.class_path可能需要是vendor/twig/twig/lib (额外的分支目录) ...

但是对于composer来说，twig.class_path实际上是不必要的，这是更好的方法(正如库博斯拉夫所指出的)。
