mongodb-error validating settings: only one positional argument is allowed

Question

I just moved to a new laptop which had mongo 3.0.0 I believe. On the new laptop I have mongo 3.0.4. and trying the script that was working on the old laptop is giving me errors. This line is giving me the error.

mongoimport --host localhost \
            -db roudy123_q \
            -collection LebaneseAmericanUniversity\(Lebanon\).json \
            --file LebaneseAmericanUniversity\(Lebanon\).json \
            --jsonArray

error validating settings: only one positional argument is allowed.

I googled the error and the only relevant result was the source code of mongoimport. So I guess it has something to do with the new version.

Answer 1

Just a wild guess...

... but the various long options should be specified using --, not -:

mongoimport --host localhost \
            --db roudy123_q \
            --collection LebaneseAmericanUniversity\(Lebanon\).json \
            --file LebaneseAmericanUniversity\(Lebanon\).json \
            --jsonArray

Maybe this particular version of mongoimport is more punctilious about that, and will treat -db ... -collection ... as positional arguments rather than keyword arguments ?

Answer 2

This error can also occur if white spaces are given without a "\" in the path to the file . Ex: This wont work:

But this would work :

Answer 3

If you are getting mongodb-error validating settings: only one positional argument is allowed.

1. Just put --file path in " ".

2.use / instead of \ in --file path.

3. Also, put --host in " ".

For example:
Suppose you are trying to import data from your local machine to server (MongoDB Atlas or your MongoDB server or locally) in your collection then follow this:

mongoimport --host "cluster0-shard-00-01-ceax1.mongodb.net:27017" --db <dbname> --type json --file "C:/Users/ranjeet/Downloads/MongoDb project/ranjeet.json" --authenticationDatabase admin --ssl --username <Username> --password <Password> --collection <CollectionName>
