我的 Express 应用程序遇到问题，我似乎无法解决，我需要一些帮助。我正在尝试将 Express 应用程序连接到 MongoDB 数据库，但似乎从未正确建立连接。情况是这样的：
My Express 应用程序配置为使用连接 URL mongodb://mongodb:27017/myapp 连接到 MongoDB 实例。 当我运行应用程序时，我看到消息“正在添加数据库支持”，但应用程序永远不会超出此点，并且永远不会完成运行。 我检查了数据库配置，它似乎是正确的，并且我还确认 MongoDB 实例已启动并且可以从其他工具访问。 我正在 Docker 容器内运行 Express 应用程序和 MongoDB，并且我已根据需要设置了网络和端口。
有谁知道可能导致此问题的原因以及如何解决该问题？我可以采取哪些额外步骤来诊断和解决 Express 应用程序中的此 MongoDB 连接问题？

重新安装docker 删除容器和镜像，然后重新安装
我已经修好了！我在
FAT32闪存驱动器上运行
docker compose up，因此“npm”永远无法完成运行。
将我的随身碟格式化为 ext4 后，我能够运行 docker compose up
