using the shiny create command in terminal (for python)

Hello,

I try to use the command shiny create in my terminal but when i do so i get an error "shiny: The term "shiny" is not recognized as the name of a command applet, function, script file or executable program. Check the spelling of the name, or if a path exists, check that the path is correct and try again.".

shiny : Le terme «shiny» n'est pas reconnu comme nom d'applet de commande, fonction, fichier de script ou programme exécutable. Vérifiez l'orthographe du nom, ou si un chemin d'accès existe, vérifiez que le chemin 
d'accès est correct et réessayez.
Au caractère Ligne:1 : 1
+ shiny create
+ ~~~~~
    + CategoryInfo          : ObjectNotFound: (shiny:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

My terminal is running in a specific folder but I can run other things like python from there. Is it a problem with the path ?

It is I believe not a big issue since I can run a basic shiny app that I copy paste. I am just wondering why this command doesn't work.

Thanks !
