所以我用Symfony 2.8.6开发了这个博客。我注意到Symfony3.1
LTS
版本可用并希望升级。因此，我修复了所有的弃用呼叫。将Symfony从2.8升级到3.1：“您的需求无法解析为可安装的一组软件包。”
我抓住Symfony3.1的composer.json文件，并试图运行
$ composer update
然而，更新失败，我得到下面的输出：
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

这是我composer.json：

我也尝试在runn时添加--with-dependencies选项ing composer update但无济于事。
有谁知道哪个包是冲突的？
只是想指出的是，3.1是不是一个长期释放。每六个月会有一次发布。下一个LTS将在2017年11月发布。http://symfony.com/roadmap?version=3.4#checker通过一切手段升级，但要确保您正确升级。 – Cerad
@Cerad：哦，我的天哪，你是对的！你认为我应该坚持2.8呢？ – D4V1D
这当然完全取决于你和你的应用程序。 – Cerad
