Nothing happens after pug is installed, why does the console say "pug" is not an external or internal command?

Question

HTML

Good day! I installed pug, node js, node via exe, and pug via the console, everything worked yesterday and the conversion via the console was elementary, one line in the console and that's it. And today nothing works, just the following inscription "pug" is issued in the console is not an internal or external command, executable program or batch file. Of the possible reasons, I can single out the change in the username from Cyrillic to Latin, because the SCSS file compiler did not work, so I changed the username, folder name, and also changed the folder name in the registry in the path to it. Could this have had an effect? What could possibly have affected? I could not google a similar problem, not a single similar request, so I decided to ask a question here. If today I can not find the answer, I think
PS I created another user, a name in Latin in advance and decided to check on it, the situation is the same, I'm desperate

Answer 1

You are probably not typing the command correctly, please check. Maybe they wrote differently when everything worked
