Composer无法安装laravel / socialite 2.0

Question

作曲家需要laravel / socialite ^ 2.0

失败，出现以下错误：

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

  Problem 1
    - Installation request for laravel/socialite 2.0 -> satisfiable by laravel/socialite[v2.0.0].
    - Conclusion: remove guzzlehttp/guzzle 6.2.2
    - Conclusion: don't install guzzlehttp/guzzle 6.2.2

    - Installation request for guzzlehttp/guzzle (locked at 6.2.2) -> satisfiable by guzzlehttp/guzzle[6.2.2].


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

Laravel版本是5.3.22

PHP版本是7.0.10

github上的composer.json of socialite2.0将依赖关系显示为guzzlehttp 5.0 / 6.0。为什么我的安装正在寻找guzzlehttp 4.0？

编辑-1：

我试图通过在composer.json require-dev中添加它来强制guzzlehttp 4.2.4。

但是，我收到以下错误：

  Problem 1
    - The requested package guzzlehttp/guzzle (locked at 6.2.2, required as 4.2.4) is satisfiable by guzzlehttp/guzzle[6.2.2] but these conflict with your requirements or minimum-stability.
  Problem 2
    - aws/aws-sdk-php 3.19.23 requires guzzlehttp/guzzle ^5.3.1|^6.2.1 -> satisfiable by guzzlehttp/guzzle[5.3.1, 5.3.2, 5.3.x-dev, 6.2.1, 6.2.2, 6.2.3, 6.3.0, 6.2.x-dev] but these conflict with your requirements or minimum-stability.
    - aws/aws-sdk-php 3.19.23 requires guzzlehttp/guzzle ^5.3.1|^6.2.1 -> satisfiable by guzzlehttp/guzzle[5.3.1, 5.3.2, 5.3.x-dev, 6.2.1, 6.2.2, 6.2.3, 6.3.0, 6.2.x-dev] but these conflict with your requirements or minimum-stability.
    - aws/aws-sdk-php 3.19.23 requires guzzlehttp/guzzle ^5.3.1|^6.2.1 -> satisfiable by guzzlehttp/guzzle[5.3.1, 5.3.2, 5.3.x-dev, 6.2.1, 6.2.2, 6.2.3, 6.3.0, 6.2.x-dev] but these conflict with your requirements or minimum-stability.
    - Installation request for aws/aws-sdk-php (locked at 3.19.23) -> satisfiable by aws/aws-sdk-php[3.19.23].

显然，aws-sdk-php需要guzzlehttp 5.3 / 6.2。 Laravel 5.3与socialite 3.0不兼容。 Socialite 2.0与guzzlehttp 5.3 / 6.2不兼容。

怎么解决这个？

TIA

我的composer.json有以下内容：

Answer 1

以下是问题的解决方法：事实证明这很简单。因为我还在学习作曲家能做什么，所以我不能早点弄明白。

在版本中从^更改为~就可以了。根据Mastering Composer - tips & tricks，波浪号（~）和插入符号（^）应该允许包中的次要版本。但是，它似乎“只注意破坏变化”优先于允许次要版本。 （至少，这是我得出的结论）。

以下是结果：

composer require laravel/socialite:~2.0
./composer.json has been updated

Answer 2

我对这个问题有一个想法。

在composer.lock中，保存您使用composer配置下载的包的哈希和版本，此时或其他时间。然后删除此文件和供应商文件夹并再次执行：

composer require laravel/socialite ^2.0

Answer 3

尝试：

composer require laravel/socialite

希望它会有所帮助。

见：Laravel documentation。

Answer 4

试试这个：作曲家需要laravel / socialite：~2.0它对我有用:)
