Cocos console version fail?

Hi people!
I downloaded cocos 3.9 and when i run cocos -v -> 2.1 show.
Someone forgot to change that ? or is fine ?

thx !

other question.

That is fine.

Cocos Studio is not open-sourced.

but…
i downloaded cocos2d-x 3.9 and cocos studio 2.3.3.

run on terminal cocos -v, it not supposed to should show the current version of cocos2d-x?

no, it shows the current version of the cocos tool, which for me is 2.1
