Composer安装/更新已停止工作

Question

突然我的Composer停止了工作。

每当我运行composer update时，它都不会在此之后继续：

正在加载包含包信息的composer存储库
更新依赖项（包括require-dev）

我尝试了另一个Laravel项目，该项目的Composer正在工作

我清除了缓存，还运行了这个命令rm -rf ~/.composer/cache

似乎什么都没发生。我把composer.lock移到另一个文件夹，从当前项目中删除，然后再次运行命令，但没有成功

这是我的composer.json文件：

Answer 1

我做了一些测试，看起来这两个包组合在一起导致了问题：

"aws/aws-sdk-php-laravel": "~3.0",
"league/flysystem-aws-s3-v2": "~1.0",

它们各自正确安装，但不能一起安装。我使用了一个全新的Laravel 5.1安装进行测试（composer create-project laravel/laravel --prefer-dist）。在仅将这两个包添加到composer.json之后，Composer被困在

更新依赖项（包括require-dev）

如果删除其中一个，则composer update运行良好。我对这两个包一无所知，但即使在-verbose模式下，组合也肯定会使Composer崩溃。

以崩溃的composer.json为例：
