Mongodb monogorestore“根目录必须是单个数据库的转储”(Mongodb monogorestore “root directory must be a dump of a single database”)

我试图将mongodump恢复到不同名称的数据库（这应该可以通过--db <dbname>开关）。

我的工作目录包含一个包含单个数据库转储的转储文件夹。

但是，当我尝试这个命令时：

mongorestore --port xxxxx --db some_destination_db

我收到以下错误：

ERROR: ERROR: root directory must be a dump of a single database ERROR: when specifying a db name with --db

我不知道为什么我得到这个，并且在google上找不到任何帮助。 有人有主意吗？

I'm trying to restore a mongodump to a differently named database (which should be possible via --db <dbname> switch).

My working directory contains a single dump folder, which contains a single db dump.

However, when I try this command:

mongorestore --port xxxxx --db some_destination_db

I get the following error:

ERROR: ERROR: root directory must be a dump of a single database ERROR: when specifying a db name with --db

I have no idea why I'm getting this, and can't find any help on google. Anyone have any ideas?

您需要包含源数据库转储目录的路径以恢复（如在MongoDB 2.6中）。

例如，如果从“twitter”恢复到“some_destination_db”，您的命令行将类似于：

mongorestore --port xxxxx --db some_destination_db dump / twitter

You need to include the path of the source db dump directory to restore from (as at MongoDB 2.6).

For example, if restoring from "twitter" to "some_destination_db" your command line would be similar to:

mongorestore --port xxxxx --db some_destination_db dump/twitter
