Question

感谢您的关注，

我已创建此APP：

// web/index.php
require_once __DIR__.'/../vendor/autoload.php';

use Silex\Application;
use Silex\Provider\TwigServiceProvider;

$app = new Application();
$app['debug'] = true;

$app->register(new TwigServiceProvider(), array(
    'twig.path' => __DIR__.'/templates',
    'twig.class_path' => __DIR__.'/../vendor/twig/twig/lib',
    'twig.options' => array('cache' => __DIR__.'/../cache'),
));

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

return $app;

但是，当我加载/加载base.html.twig的实例时，会出现此错误：

InvalidArgumentException: Identifier "twig" is not defined.

我已经按照官方教程，使用composer安装它并双重检查了所有路径......

尝试删除＆＃34; twig.class_path＆＃34;条目。

我喜欢这样，它有效：

    $options = [
        'twig.path' => ...,
        'twig.options' => [
            'strict_variables'  => false
        ]
    ];

    $this->_app->register(new TwigServiceProvider(), $options);

标识符＆＃34; twig＆＃34;未定义 - Silex Framework
