做mongorestore时，“太多的位置选择"是什么意思? [英] What does “too many positional options” mean when doing a mongorestore?

问题描述

我下载了mongodb转储.现在，我正在尝试将文件从转储移至我的mongodb位置.我正在使用mongorestore --dbpath [mongodb路径] [转储路径] cmd来执行此操作.但是我在命令提示符中看到太多的位置选项错误.谁能帮我解决这个问题.

I downloaded a mongodb dump. Now i am trying to move files from the dump to my mongodb location. I'm using mongorestore --dbpath [mongodb path] [dump path] cmd to do this. But i am seeing the too many positional options error in the command prompt. Can anyone help me with this issue.

这是命令行中的错误:

C:\Documents and Settings\>mongorestore -dbpath C:\Program Files\Mon
goDb\data\db C:\Documents and Settings\My Documents\localadventure
s\localadventures
ERROR: too many positional options

Import BSON files into MongoDB.

我今天再次尝试，并在cmd提示符下看到以下消息:

I tried again today and saw the following message in my cmd prompt:

推荐答案

C:\ Documents and Settings> mongorestore -dbpath C:\ Program Files \ MongoDb \ data \ db C:\ Documents and Settings \ My Documents \ localadventures \ localadventures 错误:位置选项过多

C:\Documents and Settings>mongorestore -dbpath C:\Program Files\MongoDb\data\db C:\Documents and Settings\My Documents\localadventures\localadventures ERROR: too many positional options

如果文件名或目录路径包含空格，则需要使用双引号将其引起来.否则，诸如mongorestore之类的命令行程序可能会合理地期望空格字符是新参数的开头，而不是先前值的延续.

If you have filenames or directory paths containing spaces, these need to be enclosed in double quotes. Otherwise command line programs such as mongorestore may reasonably expect that a space character is the start of a new parameter rather than a continuation of the previous value.

提示:如果在Windows cmd.exe shell中使用 TAB 自动完成文件名，则应自动添加正确的引用.

Tip: If you use TAB to autocomplete filenames in the Windows cmd.exe shell the correct quoting should be added automatically.

假设C:\Documents and Settings\My Documents\localadventures\包含您的mongodump文件，则预期的mongorestore用法为:

Assuming that C:\Documents and Settings\My Documents\localadventures\ contains your mongodump files, the expectedmongorestore usage would be:

> mongorestore "C:\Documents and Settings\My Documents\localadventures\localadventures"

或者，您也可以先切换到转储目录，以节省一些键入/引用.相对路径就可以了:

Alternatively, you can also change to the dump directory first to save a bit of typing/quoting. A relative path works just fine:

> cd "C:\Documents and Settings\My Documents\localadventures\"
> mongorestore localadventures

仅在直接还原到数据文件而不是不还原到正在运行的MongoDB服务器实例中时，才应包括--dbpath参数.

You should only include the --dbpath parameter if you are restoring directly to data files and not into a running MongoDB server instance.

There are some more examples of mongorestore usage in the MongoDB manual.
