我正在尝试使用twig检查用户是否经过身份验证
当我放入我的小树枝模板时:
{{ app.user.username }}
我得到了错误

首先,请注意,由于一个Symfony2.1
错误,在最近的版本中解决了一个类似的异常:
然后,请注意,该错误似乎是在类Twig_Environment
的addGlobal
函数中抛出的。您是否安装了这样的Twig扩展
不必阅读您的composer.json
,我可以建议您尝试:
清除缓存
更新composer.json中的代码,以避免出现最新的捆绑包
创建composer.phar
然后编译它以获得composer.phar
php composer.phar安装
或php composer.phar更新
,无论您的情况如何
希望能有所帮助。我会更新你的供应商并清除你的缓存。有些东西是不可靠的。好吧,唯一的办法是如果你有一个小树枝扩展,并且你使用了addGlobal('app','some value'))
您使用的是这样一个非Sensiolab捆绑包吗?您使用的确切版本是什么?您可以发布您的composer.json吗?composer.json是正确的!您是否通过最新版本的composer生成composer.phar?更新和清除缓存是否有帮助?您可以找到类似的问题。
