some solution please.

Looks like you started from a command prompt with the path set to c:\windows\system32 - you should be in the .node-red folder BEFORE running npm.

Additionally, looks like that node uses a bunch of tricks (like installing chormium and puppeteer - probably to remote control the whatsappweb page) - good luck with that hackfest.

Apart from instructing you to try again in the correct .node-red folder, I have not used it but I would personally recommend using telegram (works very well)

thanks, i can now install it in the correct npm folder, well it's a project I want to learn about.
Previously I made one in telegram and if it is simpler.

It most certainly isn't simpler. Telegram has the easiest bot interface I know of for any of the comms tools. With the help of the telegram node, it is relatively trivial to set up a bot.

AFAIK, whatsapp doesn't have any real bot API. Facebook has one but I've never managed to get it to work. Microsoft Teams has a good one - but only if you are steeped in Microsoft development - I got a basic one working with Skype for Business once but it was HARD work. Of course, much of this is because I lack the experience and certainly lack the time to learn. Or the inclination to be honest. Node-RED and Telegram make a great partnership.
