根据文档：

http://symfony.com/doc/current/book/security.html#retrieving-the-user-object

我正在尝试使用 twig 来检查用户是否已通过身份验证

当我放入我的树枝模板时：

{{ app.user.username }}

我得到错误

LogicException: Unable to add global "app" as the runtime or the extensions have already been initialized.

编辑：请按照下面的 composer.json 内容查找

没有更多细节很难回答这个问题。

首先，请注意过去也有过类似的异常，这是由于Symfony2.1最近版本已解决的一个错误：请参阅此处了解更多详细信息。

然后，请注意错误似乎是在addGlobalclass 的函数中抛出的Twig_Environment。你安装了这样的 Twig Extension 吗？

如果不阅读您的composer.json，我可以建议尝试：

  1. 清除缓存。
  2. 更新, 中的代码composer.json以避免出现最新的捆绑包。
  3. 创建composer.phar.
  4. 然后编译得到composer.phar.
  5. php composer.phar install或者php composer.phar update，无论您的情况如何。

希望能帮助到你。
