失败的作曲家需要Symfony/Mailer

Question

我正在尝试运行Composer需要Symfony/Mailer在Symfony 4项目中使用它，但是它会返回一个错误：

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - symfony/mailer[v5.4.0, ..., v5.4.8] require symfony/mime ^5.2.6|^6.0 -> found symfony/mime[v5.2.6, ..., v5.4.9, v6.0.0, ..., v6.1.1] but the package is fixed to v4.4.42 (lock file
version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - Root composer.json requires symfony/mailer ^5.4 -> satisfiable by symfony/mailer[v5.4.0, ..., v5.4.8].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

当我运行Composer -vvv -no -Plugins时，需要-NO -Scripts -no -scripts -w symfony/mailer，我得到了这样：

- symfony/mime[v6.1.0, v6.1.1] require php >=8.1 -> your php version (7.3.21) does not satisfy that requirement.

有什么想法解决的？

Answer 1

Symfony/Mailer在您的项目中固定/锁定在v4.4.42上。

运行使用的作曲家需要命令 - with-lim-repentencies（-w）查看是否解决了您的问题：

composer require -W symfony/mailer

Symfony/Mailer is您（当前）锁定文件唯一的问题。
