为什么会这样？ The requested package laravel/framework (locked at v5.5.34, required as 5.6.*)

laravel 5.4 不是引入了黄昏吗？

更新这里是 composer.json

【问题讨论】：

为什么在作曲家文件中使用laravel/framework: 5.6.*？

标签： laravel

【解决方案1】：

您需要使用支持 Laravel 5.5 的旧标签

composer require --dev laravel/dusk:^2.0

【讨论】：

在全新安装中重现了原始问题 (imgur.com/a/DAOxN)，但它适用于标签 ^2.0 (imgur.com/a/e5D6G)
我认为另一个包正在锁定我们的要求，例如laravel-admin-ext/helpers。请问edit你的composer.json文件有问题吗？
