Unrecognized arguments on Ubuntu

[reichaves]

Hi Max
I watched your talk at NICAR21. I'm Reinaldo, from Brazil
Congratulations on the project
I'm using a computer with Ubuntu 20.04 and python 3.8

I tested some commands, but only the first one worked:
csvmatch forbes-billionaires.csv bloomberg-billionaires.csv --fields1 name --fields2 Name > billionaires-in-both.csv

The others always show the error: csvmatch: error: unrecognized arguments

csvmatch cia-world-leaders.csv davos-delegates.csv --fields1 name --fields2 full_name --ignore-case > leaders-at-davos.csv
usage: csvmatch [-h] [-1 FIELDS1 [FIELDS1 ...]] [-2 FIELDS2 [FIELDS2 ...]]
[FILE1] [FILE2]
csvmatch: error: unrecognized arguments: --ignore-case

csvmatch forbes-billionaires.csv bloomberg-billionaires.csv --fields1 name --fields2 Name --output 1.name 1.rank 2.Rank > billionaires-in-both-ranked.csv
usage: csvmatch [-h] [-1 FIELDS1 [FIELDS1 ...]] [-2 FIELDS2 [FIELDS2 ...]]
[FILE1] [FILE2]
csvmatch: error: unrecognized arguments: --output 1.name 1.rank 2.Rank

Please, is there any incompatibility with Ubuntu or do I need to install other libraries?
Or did I make some silly mistake?

Best

Hi Reinaldo, thanks for coming to the session.

This is really odd. Both those commands look completely correct to me, and nothing else should need to be installed. I think you're right, it sounds like it's something about Ubuntu, but unfortunately I don't have easy access to a machine running Ubuntu at the moment.

Could you try running this, and see if it works?

csvmatch cia-world-leaders.csv davos-delegates.csv --ignore-case --fields1 name --fields2 full_name > leaders-at-davos.csv

My theory is that the fields flags are thinking that --ignore-case is the name of a column rather than a field.
