作曲家出现一些奇怪的错误，有人知道我接下来能做什么吗？我正在尝试在Laravel 2上安装oauth5.1客户端，以便我可以使用它连接到会员网络API。
Using version ~2.2 for league/oauth2-client

安装尝试的输出包含所有信息：
目前安装了paragonie/random_compat v1.4.2。您的新软件包需要paragonie/random_compat ^2.0 - 这是一个不兼容的更改(仅通过查看版本号，而不是代码)，因此Composer不能简单地安装较新的版本。
但是，已安装的某些组件需要该旧版本。您可以通过运行composer why paragonie/random_compat来找出它是哪一个，您还可以通过运行composer why-not paragonie/random_compat ^2.0来找出为什么无法安装较新版本，这可能会输出相同的信息。
总而言之，我认为关于如何解决这个问题的建议是：升级拉拉维尔。 5.1 相当旧，它取决于 ~1.4 版本中的 paragonie/random_compat。较新版本的Laravel(5.3和5.4)允许~1.4或~2.0，这将解决您的问题。
不过，我还没有深入研究这个问题。另一个组件可能也依赖于此库，并且也需要更新。拉拉维尔是我的第一个猜测。
