无法从5.7更新到Laravel 5.8

Question

我正在尝试将我的网站从Laravel 5.7升级到5.8。

我将laravel/framework中的composer.json更改为“ 5.8。*”，然后运行composer update，但是来自作曲家的结果是：

Loading composer repositories with package information
Updating dependencies (including require-dev)

    You can run './vendor/bin/upgrade-carbon' to get help in updating carbon and other frameworks and libraries that depend on it.

我什至尝试更新composer.lock中的版本号，但这也不起作用，它只是将版本还原为“ 5.7.28”。

也尝试删除composer.lock，但是得到了类似的结果，这里是：

我这样做了：

composer require laravel/framework ^5.8

结果是：

./composer.json has been updated

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

有什么想法吗？

Answer 1

尝试使用此

composer require laravel/framework ^5.8 --update-with-dependencies

  

-update-with-dependencies：还要更新新要求的程序包的依赖关系，除了那些作为根要求的程序包。

或者在更新软件包时

composer update laravel/framework --with-dependencies

  

-with-dependencies：将白名单软件包的依赖项添加到白名单中，除了那些是根要求。

换句话说，这将更新laravel/framework之外的其他软件包，这是更新Laravel 5.8所必需的。

Answer 2

您是否尝试按照错误消息中的建议运行./vendor/bin/upgrade-carbon？我最近在不同的框架上遇到了类似的问题，但是将Carbon升级到v2之后，我可以更新框架和其他软件包。
