Composer版本匹配错误laravel + spatie medialibrary

Question

我尝试使用laravel new <appname>通过laravel安装程序创建一个新的laravel应用程序。

这是没有问题的。一旦我尝试安装spatie/medialibrary，我就会得到以下无法解释的错误：

$ composer require "spatie/laravel-medialibrary:^9.0.0"
./composer.json has been updated
Running composer update spatie/laravel-medialibrary
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - spatie/laravel-medialibrary[9.0.0, ..., 9.6.4] require spatie/image ^1.4.0 -> satisfiable by spatie/image[1.4.0, ..., v1.x-dev].
    - spatie/image[1.10.0, ..., v1.x-dev] require league/glide ^1.6 -> satisfiable by league/glide[1.6.0, 1.6.1, 1.7.0, 1.x-dev].
    - spatie/image[1.7.5, ..., 1.9.0] require league/glide ^1.4 -> satisfiable by league/glide[1.4.0, ..., 1.x-dev].
    - league/glide[1.4.0, ..., 1.x-dev] require intervention/image ^2.4 -> satisfiable by intervention/image[2.4.0, ..., 2.5.1].
    - intervention/image 2.4.x-dev is an alias of intervention/image dev-master and thus requires it to be installed too.
    - spatie/image 1.10.3 requires league/glide ^2.0 -> satisfiable by league/glide[2.0.0, 2.0.x-dev].
    - intervention/image[dev-master, 2.4.0, ..., 2.5.1] require guzzlehttp/psr7 ~1.1 -> found guzzlehttp/psr7[1.1.0, ..., 1.x-dev] but the package is fixed to 2.0.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - league/glide 2.0.x-dev requires guzzlehttp/psr7 ^1.1 -> found guzzlehttp/psr7[1.1.0, ..., 1.x-dev] but the package is fixed to 2.0.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - league/glide 2.0.0 requires league/flysystem ^2.0 -> found league/flysystem[2.0.0-alpha.1, ..., 2.x-dev] but the package is fixed to 1.1.4 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - spatie/image 1.4.0 requires symfony/process ^3.0 -> found symfony/process[v3.0.0-BETA1, ..., 3.4.x-dev] but the package is fixed to v5.3.2 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - spatie/image[1.4.1, ..., 1.7.4] require symfony/process ^3.0|^4.0 -> found symfony/process[v3.0.0-BETA1, ..., 3.4.x-dev, v4.0.0-BETA1, ..., 4.4.x-dev] but the package is fixed to v5.3.2 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - Root composer.json requires spatie/laravel-medialibrary ^9.0.0 -> satisfiable by spatie/laravel-medialibrary[9.0.0, ..., 9.6.4].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

即使我尝试允许composer自动升级/降级不匹配的包，我仍然得到一个类似的错误：

$ composer require "spatie/laravel-medialibrary:^9.0.0" -W                                                                                                                             
./composer.json has been updated

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires laravel/framework ^8.0, found laravel/framework[v8.0.0, ..., 8.x-dev] but these were not loaded, likely because it conflicts with another require.

这也是我的composer.json：

}

编写器版本：Composer version 2.1.3 2021-06-09 16:31:20

PHP版本：

$ php -v
PHP 7.4.9 (cli)

我不明白这里的问题是什么，全新创建的应用程序完全满足了对laravel安装的要求，而媒体库包需要版本7+中的laravel框架。

我是不是遗漏了什么，他们告诉我有什么问题？

谢谢

您可以通过运行以下命令忽略平台要求

 composer install --ignore-platform-reqs

或升级，或降级

composer install --with-all-dependencies

同时删除composer.lock文件(在安装之前)

sudo rm  composer.lock
