【问题描述】：

我不知道我是否遗漏了一些明显的东西。所以，我正在尝试将 Symfony 从 3.3.2 更新到 3.4。我用

检查了问题

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

我收到以下反馈：

我不明白的是我必须安装新版本的 twig 但同时我不应该安装这一事实之间的矛盾。我检查了 Symfony 的文档，但一无所获。无论如何，我尝试使用各种版本的树枝进行更新，但没有成功。我仍然可以遵循这个解决方案，但我担心我会弄乱我的代码。

How to properly update Symfony3.3 to Symfony4.X?

我在另一个论坛上看到了一个解决方案。我试过了，所以我删除了 composer.lock 和 vendor 目录。现在重新下载了软件包，但在此过程中我收到以下错误：

[RuntimeException]                                                           
An error occurred when executing the "'cache:clear --no-warmup'" command:  
In ParameterBag.php line 102:
You have requested a non-existent parameter "mailer_port". Did you mean this: "mailer_host"?`

有人知道应该怎么做吗？

【问题讨论】：

symfony/symfony v3.4.0 requires twig/twig ^1.35|^2.4.4 -> 你有 twig 1.35 或 2.4.4 及更高版本吗？看起来你仍然以 Symfony 3 代码为目标......也许更新你的 composer.json 文件以反映新的变化
我目前安装了 twig 1.35.4。如果我还是用 php composer.phar update 进行更新，它会给我帖子中的 EDIT1 错误。
但是您是否尝试过手动更新 composer json？
如果通过手动更改您的意思是修改 composer.json 中的 require 对象，我这样做是为了适应 composer 的先前请求，直到我陷入此循环。我在帖子中上传了我的新旧作曲家。

标签： symfony twig composer-php

【解决方案1】：

尝试回写"twig/twig": "^1.0||^2.0"，然后将"sensio/framework-extra-bundle": "^3.0.2" 更改为"sensio/framework-extra-bundle": "^5.0.0"，这是我在您的composer.json 和新Symfony 3.4.16 项目的composer.json 之间看到的唯一区别。

【讨论】：

然后我得到以下关于树枝的错误。 The requested package sensio/framework-extra-bundle (installed at v3.0.26, required as ^5.0.0) is satisfiable by sensio/framework-extra-bundle[v3.0.26] but these conflict with your requirements or minimum-stability。是否有可能因为我将整个网站文件夹复制到另一台也运行 LAMP 的计算机来尝试更新而不会弄乱原始文件而丢失了某些东西？
谢谢大家的帮助！我没有找到答案。相反，我安装了一个新的 Symfony 3.4 并将我的项目复制到其中。我不得不做一些改变（只是用树枝，这是更新的问题），但它现在可以工作了。无论如何，如果有人有想法，我仍然有兴趣知道错误是什么。
很抱歉没有回答您的最后一个问题...很高兴您能成功！
