After creating a Vue 3 project, adding Vuetify 3 Alpha, when I run "npm run serve", this is the error I get. I tried without adding Vuetify 3 Alpha and the Vue 3 project starts fine, it's just after adding the Vuetify that the error appears.

I had the same error after running vue add vuetify
Run npm update and re-create the project again.
Also make sure you are on the latest versions of the following.
node -v && vue -V && npm -v
@Mishka's solution worked for me, but I did npm update --force to make it working.
