How to install or remove vue/cli of a specific version?

Question

npm

I had @vue/cli 3.10.0 installed globally But for some reason I got an error when installing vuetifyjs

Command vue init requires a global addon to be installed.
Please run npm install -g @vue/cli-init and try again.

After npm install @vue/cli -g
version 3.11.0 was installed
And now the message

New minor version of npm available! 6.9.0 -> 6.11.2       │
   │   Changelog: https://github.com/npm/cli/releases/tag/v6.11.2   │
   │               Run npm install -g npm to update!

I don't want to update npm. there is already a project with version "@vue/cli: 3.10.0 and npm 6.9.0
