tymon/jwt-auth包在laravel 5.8中显示错误

Question

我安装了Laravel 5.8的一个新项目，但当我安装JWT Auth包时，

composer require tymon/jwt-auth

它显示了一个错误：

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

我什么都试过了，但似乎没有一样对我有效。然后，我检查这个链接https://github.com/tymondesigns/jwt-auth/issues/1764

如何解决这个问题？

Answer 1

为了在Laravel5.8中安装JWTAuth，您需要使用以下命令

composer require tymon/jwt-auth:dev-develop

Answer 2

是的，github上有一个open issue。解决方案：composer require tymon/jwt-auth:1.0.0-rc.4.1

要在Laravel 5.8中安装和正确使用它，您需要"tymon/jwt-auth": "1.0.0-rc.4.1"。不是0.5.x，甚至不是1.0.x。

我使用它，一切都很好。

Answer 3

此程序包尚不支持PHP 8.0

您可以添加composer require tymon/jwt-auth --ignore-platform-reqs

--ignore-platform-reqs适合我，而且你需要最新的作曲家。
