Answer 1

This is a problem related to npm. You can get this error when the cache file gets corrupted. Clearing the cache solves the problem. Can you try this?

npm cache clean --force

Answer 2

you can clear cache by running these command:

npm cache clean --force

• linux system:

run command as root

sudo npm install -g @vue/cli 

• windows system

open command prompt as adminstrator then run:

npm install -g @vue/cli
