php - Symfony - 将旧项目 (v 2.6) 升级到 3.4

Question

我有一个 Symfony Web 应用程序需要从 Symfony 2.6 升级到 3.4。是否有一个标准化的、简单的 composer.json 来显示当前版本所需的内容？ github 上的演示应用程序文件似乎充满了一堆我不完全确定我需要的额外内容。理想情况下，我想更新现有的 composer.json 并消除可能出现的向后兼容性问题。

编辑:我现在的 Composer 是 -

尝试运行composer create-project symfony/framework-standard-edition - 它将使用默认的composer.json设置一个简单的项目。看起来像这样:

    "name": "name",
    "license": "proprietary",
    "type": "project",

    },
    "autoload-dev": {
