推荐答案

如果你输入 db 你会看到你在名为 test 的数据库上，但它不会显示在列表中，即发生是因为测试数据库不包含任何文档，它是空的.如果您希望在键入 show dbs

If you type db you will see that you are on database named test, but it won't be shown in list, that happens because test db doesn't contain any document it is empty. You need to create at least one document in test database if you want it to be shown in list after typing show dbs
