Symfony 4.4 - Swift Mailer 安装失败

Question

我是 Symfony 的初学者，想知道如何处理以下安装问题： 我正在使用 Symfony 4.4 并尝试安装 Swift Mailer。按照此 link 上的文档，当我运行以下命令

composer require symfony/swiftmailer-bundle 

时，我收到此错误消息：

您的要求无法解决为一组可安装的 包裹。

问题1

• symfony/web-server-bundle 已锁定到版本 v4.4.0，并且未请求此包的更新。
• symfony/web-server-bundle v4.4.0 需要 php ^7.1.3 -> 你的 php 版本（8.0.12）不满足该要求。

问题2

• laminas/laminas-code 3.4.1 需要 php ^7.1 -> 你的 php 版本 (8.0.12) 不满足该要求。
• symfony/proxy-manager-bridge v4.4.34 需要 Friendsofphp/proxy-manager-lts ^1.0.2 -> 可满足 Friendsofphp/proxy-manager-lts[v1.0.5].
• friendsofphp/proxy-manager-lts v1.0.5 需要 laminas/laminas-code ~3.4.1|^4.0 -> 可满足 laminas/laminas-code[3.4.1]。
• symfony/proxy-manager-bridge 已锁定到版本 v4.4.34，并且未请求更新此软件包。

知道如何处理吗？

Answer 1

尝试更改composer.json

来自：

"symfony/web-server-bundle": "4.4",

致：

"symfony/web-server-bundle": "4.4.*",

然后尝试运行：

composer update

为了获取最新版本的依赖项并更新composer.lock文件：https://getcomposer.org/doc/03-cli.md#update-u,

然后：

composer require symfony/swiftmailer-bundle

我建议您从 swiftmailer 更改为 symfony mailer (https://symfony.com/doc/4.4/mailer.html)，因为 swiftmailer 已达到其使用寿命： https://symfony.com/blog/the-end-of-swiftmailer
