我已按照以下链接上的说明进行操作：

https://www.php.net/manual/en/mongodb.installation.windows.php

但是，当我尝试以下其中一个comands：

composer require jenssegers/mongodb

composer require jenssegers/mongodb:dev-develop

composer require jenssegers/mongodb --ignore-platform-reqs

它们都返回相同的错误：

 Using version ^3.7 for jenssegers/mongodb
 ./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.

我所尝试的：

• 重启xampp
• 许多不同版本的mongodlls。线程安全和非线程安全。我的phpinfo页面显示线程安全启用，所以我想我应该选择线程安全版本，但我已经尝试了两个以防万一，但都不会工作。我甚至尝试了x86版本只是incase。
• 我已经尝试了作曲家要求jenssecers/mongodb： dev-Development和作曲家要求jenssecers/mongodb--忽视平台-reqs，但出现了相同的错误

有什么问题吗？

php版本7.4。9

laravel版本8.6。0

我尝试使用的mongodb dll是最新的（php_mongodb-1.8.0-7.4-ts-vc15-x64），正如我所说，我也尝试过旧的
