我正在使用作曲家来管理项目中的依赖项。当我第一次进行“ composer安装”时，它会工作，创建供应商文件夹并创建composer.lock文件。然后，当我删除供应商文件夹并再次运行“ composer install”时，它将失败。
$ composer install

Problem 1
- Installation request for drupal/drupal-driver v2.0.0-alpha3 ->
satisfiable by drupal/drupal-driver[v2.0.0-alpha3].
- drupal/drupal-driver v2.0.0-alpha3 requires drupal/core-utility ^8.4
-> no matching package found.
Problem 2
- drupal/drupal-driver v2.0.0-alpha3 requires drupal/core-utility ^8.4
-> no matching package found.
- drupal/drupal-extension dev-master requires drupal/drupal-driver
^2.0.0 -> satisfiable by drupal/drupal-driver[v2.0.0-alpha3].
- Installation request for drupal/drupal-extension dev-master ->
satisfiable by drupal/drupal-extension[dev-master].
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
这里可能是什么原因？有什么建议吗？
