Step 1: Configure path (already configured can be skipped)

npm config get prefix

Copy the obtained path information, go toDesktop>Right-click Computer> Properties>Advanced System Settings>Environment Variables
Create a new variable NPM in System Variables. The variable value is the path information copied before, usually C:\Users\xxx\AppData\Roaming\npm
Then find path in System Variables and add %NPM%. Keep clicking Save.

The second step: install cnpm

npm install -g cnpm --registry=https://registry.npm.taobao.org

The third step (the most critical!)

npm i npm -g npm i @vue/cli -g //如果还报错也没关系，继续执行下面的命令

cnpm i @vue/cli -g
