我正在尝试用 adldap2/adldap2-laravel 和 adldap2/adldap2 替换 strebl/l5-ldap-auth 和 strebl/adldap 包，但是在尝试使用 Composer 安装时出现以下错误：
Your requirements could not be resolved to an installable set of packages.
完整的错误信息如下：
sudo php composer.phar require adldap2/adldap2
Using version ^6.0 for adldap2/adldap2
./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.

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.
Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.
Installation failed, reverting ./composer.json to its original content.
我怀疑这条线
requires illuminate/contracts 5.3.* -> no matching package found
是问题的根源。
查看 Github 上最新的 Laravel 开发源代码，在我看来，最新版本的Illumination/contracts 是 5.2，而不是 5.3，所以可能是某个地方出现了拼写错误。
有什么方法可以覆盖这个要求，或者强制安装 adldap2/adldap2-laravel 和 adldap2/adldap2？
