安装失败，正在将 ./composer.json 还原为其原始内容。

我已经尝试了所有我能想到的东西，但现在如果有人有任何建议或者可以引导我走向正确的方向，那我就没有想法了

您使用的是旧版本的 Lumen，当前版本的 illuminate/mail 不支持该版本。

您需要安装支持illuminate/container v6.18.10的最新版本 如果你检查这个包的最新修订标签，支持illuminate/container v6.18.10的最早版本是这个：https://github.com/illuminate/mail/blob/v6.18.10/composer.json在那里你可以找到这一行

    "require": {
        ...
        "illuminate/container": "^6.0",
        ...
    },

要安装此特定版本，您需要使用：

composer require illuminate/mail:6.18.10
