Laravel Framework版本使用包mailjet/laravel-mailjet的问题

Question

我在使用mailjet/laravel-mailjet时遇到了一个问题，似乎是版本问题。我使用的是Laravel Framework 5.6.33，我得到了

Can only install one of: laravel/framework[v5.6.39, 5.4.x-dev].

我已经改变了我的composer.json，现在我使用的是Laravel Framework 5.6.39，但是我仍然有同样的问题

 $ php artisan --version
Laravel Framework 5.6.39

当我尝试安装mailjet/laravel-mailjet时，答案就在这里

$ composer require mailjet/laravel-mailjet
Using version ^1.1 for mailjet/laravel-mailjet
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Can only install one of: laravel/framework[v5.6.39, 5.4.x-dev].
    - Can only install one of: laravel/framework[5.4.x-dev, v5.6.39].
    - Can only install one of: laravel/framework[5.4.x-dev, v5.6.39].
    - mailjet/laravel-mailjet 1.1.0 requires laravel/framework 5.4.* -> satisfiable by laravel/framework[5.4.x-dev].
    - Installation request for mailjet/laravel-mailjet ^1.1 -> satisfiable by mailjet/laravel-mailjet[1.1.0].
    - Installation request for laravel/framework 5.6.39 -> satisfiable by laravel/framework[v5.6.39].

Answer 1

第四行解释了这一切。

mailjet/laravel-mailjet 1.1.0 requires laravel/framework 5.4.*

因此，您不能使用v5.6.39，只能使用5.4.*
