In case someone stumbles on this, the error is received when Vue CLI assumes you're building a single file component, and thus requires you to hyphenate component name:

Bad

npx vue-cli-service build --target wc --name mycomponent './src/components/Button.vue'

Good

npx vue-cli-service build --target wc --name my-component './src/components/Button.vue'

Personally, I was receiving this error when I forgot to wrap my [entry] path in quotes (which was not that apparent when the command was in package.json scripts), when creating a bundle that registers multiple components. Which confused me, because I was sure I don't need to hyphenate the name in this case. But what probably happened was that vue-cli discared entry value as invalid and then just took first .vue file from components dir as entry, thus assuming it was supposed to be a single file component.

Error (notice missing quotes)

npx vue-cli-service build --target wc --name companyname ./src/components/*.vue

Success

npx vue-cli-service build --target wc --name companyname './src/components/*.vue'
