Steps to reproduce

On a brand new vue cli project created with vue create I want to run a vue web component bundler. I run npx vue-cli-service build --target wc --name my-element *.vue from src folder and it compiles nicely. After that, every next try ends up with 404error from https://registry.npmjs.org/vue-cli-service.
It runs again after I remove package-lock and node_modules and npm install:
rm -rf node_modules package-lock.json && npm install
What am I doing wrong ?

What is expected?

to rebuild web component every time I want it

What is actually happening?

it runs only once, on a clean project and then got error 404 every next time

removing package-lock and node_modules , then 'npm install' helps
