Vue : command not found after installing #vue/cli - vue.js

Question

I don't know why isn't working for me. I opened powershell as administrator and run npm install -g #vue/cli. I have done uninstalling vue-cli and restalling again doesn't work. Here is my error
PS C:\WINDOWS\system32> npm install -g #vue/cli

Answer 1

Adding %APPDATA%\npm to the PATH fixed my problem

Answer 2

install using sudo
sudo yarn global add #vue/cli

Answer 3

At windows:
First step: %path%;%appdata%\npm;C:\Program Files\nodejs;C:\Users\User.npm-global;C:\Program Files (x86)\bin\
in environment variable
second step: https://classic.yarnpkg.com/en/docs/install/#windows-stable
install yarn or npm
third step: run window shell as administrator
set-executionpolicy unrestricted
Forth step : yarn global add #vue/cli
Result:
C:\Users\User>vue --version
#vue/cli 4.5.15
