php - 即使没有明显的冲突，Composer 也不会安装

标签 php laravel composer-php

我一直在为这个问题苦苦挣扎。我正在从 Laravel 6 升级到 7， Composer 在这里不合作。它输出了一个巨大的依赖关系故事，这对我来说根本没有任何意义。

我确保我的依赖项支持 Laravel 7.0，我可能错过了一些东西，但如果我这样做了， Composer 肯定不会突出显示它。

我也删除了 composer.lock 和 vendor。

这是我的 composer.json:

当我执行 composer install 时，大约需要 3 分钟(禁用 xdebug)，并输出:

有人知道这是怎么回事吗？好像它说 laravel/framework 想要包含 symfony/http-kernel 和 symfony/http-kernel 想要包含 symfony/事件调度程序，但我不明白这有什么问题？为什么它甚至是一个错误？

最佳答案

在结论列表的末尾，它告诉您它要安装 php-tmdb/api: 2.1.x-dev .

如果您访问该项目的存储库，您会发现有一个可用的 v3。

v2 php-tmdb/api想要"symfony/event-dispatcher": ">=2.4,<5" - 这与 laravel 的约束冲突。

解决方案:要求php-tmdb/api: 3.0

关于php - 即使没有明显的冲突，Composer 也不会安装，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/61711589/
