我的PHP版本是7.0.10，我使用wamp。

Answer 1

您的PHP版本是5.6

This package requires php >=7.0 but your PHP version (5.6.25) does not satisfy that requirement.

因此，将PHP版本更改为PHP 7.0并运行：

composer install

Answer 2

我过去有类似的问题..这发生在wamp ...使用命令提示符检查你的php版本..有时wamp显示v7但项目在后台继续使用旧版本。或者在laravel上创建一个显示php版本的路线..它将确认问题是什么。

Answer 3

尝试使用composer install --ignore-platform-reqs

Answer 4

您需要删除composer.lock文件＆amp;再次运行composer install

无法将Laravel 5.4更新为5.5作曲家
