【问题描述】：

我想将我的旧 Symfony 项目从 2.8 升级到 4.0，但我在从 2.8 升级到 3.4 时堆积如山。我用这个教程升级Moving to Symfony 3.4。

我在尝试通过 composer Composer Upgrade Errors 更新时遇到一些错误：

# php composer.phar update symfony/symfony --with-dependencies

Dependency "twig/twig" is also a root requirement, but is not explicitly whitelisted. Ignoring.
Dependency "ircmaxell/password-compat" is also a root requirement, but is not explicitly whitelisted. Ignoring.

说实话，上一次我在 3 年前在 Symfony 中做某事时，但我真的很想要我的旧项目。如果有人可以帮助我找出问题所在。

我已经尝试将 minimum-stability:stable 更改为 minimum-stability:dev，但没有成功。

【问题讨论】：

您是否尝试手动将提及的依赖项更新为所需版本？

手动你的意思是在json文件里面？是的，我做到了。也许我应该尝试使用作曲家来更新它？

像这样使用作曲家composer require symfony/monolog-bundle:^3.1.0等

您好，我尝试这样做，但在 require sensio/framework-extra-bundle:^5.0.0 和 require sensio/symfony 上也存在一些问题： ^3.4.*。来自TUTORIAL 的其他人都可以。

你可以用composer require手动解决每一个新问题，不要太多

【参考方案1】：

升级到 3.4.*，因为它是最新的 LTS 版本。 4.4 出来时应该更新到版本 4（它将是 LTS 版本）。

尝试调整您的配置，如下所示并运行作曲家更新。以下配置带有自动装配。考虑是否要使用它，但我建议，因为使用类型提示在构造函数中获取服务/控制器中的依赖项会更舒服。

1) Composer.json

"symfony/symfony": "3.4.*",
"sensio/distribution-bundle": "^5.0.19",
"sensio/framework-extra-bundle": "^5.0.0",
"twig/twig": "^1.0||^2.0",
"symfony/monolog-bundle": "^3.1.0",

2) app/config/services.yml

services:
    _defaults:
        autowire: true # Automatically injects dependencies in your services
        autoconfigure: true
        public: false
        bind:
            # Nice feature here. Local Binding. Read about it at documentation.


    # makes classes in AppBundle available to be used as services
    AppBundle\:
        resource: '../../src/AppBundle/*'
    # exclude directories || files (if service is unused, it will be removed anyway)
        exclude: '../../src/AppBundle/Entity,Repository,Tests'
    AppBundle\Controller\:
        resource: '../../src/AppBundle/Controller'
        public: true
        tags: ['controller.service_arguments']

3) AppBundle/Resources/config/services.yml

   services:
    _defaults:
        autowire: true
        autoconfigure: true
        public: false

【讨论】：

感谢您的回答。今晚我试试：）

谢谢，它帮助了我。我需要在 composer.json 中做更多的调整并且更新了 :) 现在我需要修复一些代码问题。非常感谢:)

我很高兴，它帮助了你。 :)
