卷已存在，但不是由 Docker Compose 创建的

Question

这是我在新项目或任何其他项目上使用 ddev start 后得到的结果。我清除了所有 docker 映像、卷等...并且问题再次重复...

有没有人有同样的问题，它与版本有什么关系：

• Docker 版本 20.10.11
• Docker Compose 版本 2.2.0
• ddev版本v1.18.0

此问题已在 DDEV v1.18.2+（和 v1.19+）中解决，请升级。这是 docker-compose 2.2.0+ 中的一个错误 - 请参阅https://github.com/drud/ddev/issues/3404了解上下文。
