Why are there problems installing vue-cli?

Question

Vue.js

Strange, but for some reason I can't install vue-cli. Terminal throws an error

PS C:\Users\Skwo\Desktop\vue.new.project> npm i @vue/cli
Нераспознанный токен в исходном тексте.
строка:1 знак:7
+ npm i  <<<< @vue/cli
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : UnrecognizedToken
 
PS C:\Users\Skwo\Desktop\vue.new.project> npm install -g @vue/cli
Нераспознанный токен в исходном тексте.
строка:1 знак:16
+ npm install -g  <<<< @vue/cli
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : UnrecognizedToken

Such responses to different attempts.
I checked if the packages are installed globally, it may need to be reinstalled.
Vue didn't find any packages..

Answer 1

the problem turned out to be that you need to quote: @vue/cli , that is - "@vue/cli"
ps
it is not clear why such a problem, and why developers do not write about it and how to solve it, why you need to look for an answer to overflow
