Twig 细枝未装入Silex中

我正在尝试使用运行应用程序。我有与示例中类似的源代码：

但我得到了一个错误：

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

这个问题也是。

解决方案是使用和。

使用这种方法，您的twig.class\u路径可能需要是

供应商/twig/twig/lib

（额外的twig目录）

但是对于composer来说，twig.class_路径实际上是不必要的，这是更好的方法（正如kuboslav所指出的）
