Vue：安装@vue/cli 后找不到命令

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

将%APPDATA%\\npm添加到PATH修复了我的问题

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
