我正在尝试使用 Symfony 5 安装 LiipImagineBundle，但出现此错误：
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Installation request for liip/imagine-bundle ^2.2 -> satisfiable by liip/imagine-bundle[2.2.0].
- liip/imagine-bundle 2.2.0 requires symfony/asset ^3.4|^4.2 -> no matching package found.
Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.
- It's a private package and you forgot to add a custom repository to find it
Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.
Installation failed, reverting ./composer.json to its original content.
我怎样才能解决这个问题 ？
