Question

与作曲家一起出现一些奇怪的错误，有谁知道接下来我能做什么？我正在尝试在Laravel 5.1上安装oauth2客户端，以便我可以使用它连接到联盟网络API。

Using version ~2.2 for league/oauth2-client
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)

Installation failed, reverting ./composer.json to its original content.

my composer.json：

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（只需查看版本号，而不是代码），因此Composer无法简单地安装新版本。

但是，已安装的某些组件需要旧版本。您可以通过运行composer why paragonie/random_compat找出它是哪一个，并且您还可以通过运行composer why-not paragonie/random_compat ^2.0来找出无法安装新版本的原因，这可能会输出相同的信息

总而言之，我认为如何解决这个问题的建议是：升级Laravel。 5.1相当陈旧，它取决于版本~1.4中的paragonie / random_compat。较新版本的Laravel（5.3和5.4）允许~1.4或~2.0，这可以解决您的问题。

但是，我还没有深入研究这个问题。有可能另一个组件也依赖于此库，并且还需要更新。 Laravel是我的第一个猜测。

为什么我不能安装oauth2客户端？
