in mongodb 3.0 or above, we should specify the database name to restore
在mongodb 3.0及以上，我们应该指定要恢复的数据库名称
mongorestore -d [your_db_name] [your_dump_dir]

You probably saw this error:
你可能看到了这个错误：
ERROR: don't know what to do with file [dump]
错误：不知道如何处理文件 [转储]
Which means in this case, that there is no file or directory called dumpin your current working directory. So, Try this first cd c:/hw1-1/(or whatever the correct syntax is on Windows, I can't test it.) Alternatively you can specify the full path to the dumpdirectory:
这意味着在这种情况下，dump当前工作目录中没有调用文件或目录。因此，请先尝试此操作cd c:/hw1-1/（或 Windows 上的任何正确语法，我都无法测试。）或者，您可以指定dump目录的完整路径：
mongorestore c:/hw1-1/dump

If you're using mongoexportto create the dump, be sure to use mongoimportrather than mongorestoreto load it.
如果您正在使用mongoexport创建转储，请确保使用mongoimport而不是mongorestore加载它。

This error message "don't know what to do with file" can also occur if you have a BSON file that does not have a .bson file extension.
如果您的 BSON 文件没有 .bson 文件扩展名，也会出现此错误消息“不知道如何处理文件”。
Generally this isn't a problem since mongodumpgenerates the files with .bson extensions, but in my case I had a BSON file that was not generated by mongodumpand had a different file extension.
通常这不是问题，因为mongodump生成带有 .bson 扩展名的文件，但在我的情况下，我有一个 BSON 文件，它不是由 .bson 生成的mongodump并且具有不同的文件扩展名。

I'm on version 3.2 windowsand my mongorestoreseems to have a bug:
我在version 3.2 windows，我mongorestore似乎有一个错误：
If I specify /db:database_nameor /d database_nameI get the error:
如果我指定/db:database_name或/d database_name出现错误：
don't know what to do with subdirectory "dump\database_name", skipping...
Instead if I let it run on the whole dump directory it seems to work. The command I used is:
相反，如果我让它在整个转储目录上运行，它似乎可以工作。我使用的命令是：
mongorestore /host:remote_host dump
mongorestore /host:remote_host dump
My current directory structure is:
我当前的目录结构是：
.
..
dump
dump\database_name

I got this error when I had a collection matching the name of the one I was trying to restore present in Mongo ended up going into Mongo and deleting it using db.m101.drop();
当我有一个与我在 Mongo 中尝试恢复的集合的名称相匹配的集合最终进入 Mongo 并使用 db.m101.drop() 删除它时，我收到了这个错误；

It took me some time to figure out the options for mongorestore , after i had kept getting this error for some time .
在我不断收到此错误一段时间后，我花了一些时间来找出 mongorestore 的选项。
a) No running instances of mongod .
a) 没有正在运行的 mongod 实例。
b) mongorestore -v -host localhost:27017 --dbpath "Actual Path for the Mongo DB- set in config" "Location where the dump is"
b) mongorestore -v -host localhost:27017 --dbpath "Actual Path for the Mongo DB- set in config" "Location where the dump is"
Using dbpath , allows to run this command without any running version of mongod . And this resolved my error .
使用 dbpath ，允许在没有任何正在运行的 mongod 版本的情况下运行此命令。这解决了我的错误。
