Problems while setting up vue-cli
Well, problem was solved by simply deleting everything related to vue-cli installed before. And re-installing vue-cli.
yarn add @vue/cli-service
or
npm install @vue/cli-service
is what worked for me
I follow these commands, It's work fine for me.
npm install -g vue-cli
npm install -g vue
Edit the System environment variables, and enter the following path, and if still having a problem just try to add a path in System User Variables
C:\Program Files\nodejs\node.exe;
C:\Users\{UserName}\AppData\Roaming\npm
Check vue installed in C:\Users{UserName}\AppData\Roaming\npm
