[Vuejs]-Updated Vue to 3.2.3. vue –version shows as 3.0.1 still… How to fix?

Try running npm install -g @vue/cli then reload your terminal.

You need to uninstall vue-cli, and then install @vue/cli.
Here is how:

npm uninstall -g vue-cli  
npm install -g @vue/cli

3 steps to update from vue 3 lower version to the latest:

• npm install -g @vue/cli
• vue upgrade
• npm i

Maybe you have npm and yarn installed.
Try npm update --global and yarn global upgrade.

Good luck!!!
