Question

我安装了laravel 5.8，然后执行了composer require tcg/voyager:1.3.2。我没有使用composer require tcg/voyager，因为它显然不支持laravel 5.8。但是，它不断失败并引发此问题：

Problem 1
    - Can only install one of: league/flysystem[1.1.3, 1.0.x-dev].
    - Can only install one of: league/flysystem[1.0.x-dev, 1.1.3].
    - Can only install one of: league/flysystem[1.0.x-dev, 1.1.3].
    - tcg/voyager v1.3.2 requires league/flysystem ~1.0.41 -> satisfiable by league/flysystem[1.0.x-dev].
    - Installation request for tcg/voyager 1.3.2 -> satisfiable by tcg/voyager[v1.3.2].
    - Installation request for league/flysystem 1.1.3 -> satisfiable by league/flysystem[1.1.3].

我尝试在航海家之前先安装composer require league/flysystem:1.1.3，但仍然失败，并出现相同的错误。我在这里迷路了。

Answer 1

您是否检查过league/flysystem是否已安装？根据该错误消息，它安装在v1.1.3中，而tcg/voyager需要v1.0。*-这不兼容。

flysystem的v1.1相当新，只有Voyager的当前dev分支包含对此的修补程序。

要解决这种情况，您可以运行composer require league/flysystem:"~1.0.41"

安装Laravel 5.8 + Voyager时Composer失败
