Answer 1

install vue-cli if you haven't yet
sudo npm install -g #vue/cli
OR update to latest
sudo npm update -g #vue/cli
then create a new project with
vue create hello-world
then select vue 3 project
Including comment from #Eazash:
You need to verify your npm cache with npm cache verify and then try installing vue-cli. If that doesn't work, try clearing the cache altogether with npm cache clean --force
could also try with sudo privileges: sudo npm cache verify and sudo npm cache clean --force
