【问题描述】：

我刚刚将我的 Symfony 2.2 安装升级到 Symfony 2.3。我本可以让“composer update”正常运行，但是这导致我的应用程序中的每条路由都返回一个空白页。如果我检查我的 JavaScript 控制台上的网络选项卡，我会看到一个 500 Internal Server Error 被抛出，但不知道是什么原因造成的。有任何想法吗？这是我的 composer.json 文件：

【问题讨论】：

您是否在 web/app.php 中设置了 debug true 以显示错误？ ($kernel = new AppKernel('dev', true);)

标签： symfony symfony-2.2 symfony-2.3

【解决方案1】：

需要在 2.3 中手动启用。

调试::启用();

见：https://github.com/symfony/symfony-standard/blob/2.3/UPGRADE-2.3.md

【解决方案2】：

检查您的日志以查找异常...app/logs/dev.log 或 app/logs/prod.log，具体取决于您尝试访问的环境。

并清除你的缓存:-)

app/console cache:clear

【解决方案3】：

symfony >= 2.3 不支持从您的 composer.json thouse 版本更新这些行

之前

"jms/security-extra-bundle": "1.5.*",
"jms/di-extra-bundle": "1.4.*",

之后

"jms/di-extra-bundle": "dev-master",
"jms/security-extra-bundle": "dev-master",

问候。
