Actual behavior

Error: Build failed with 1 error:
node_modules/vue-demi/lib/index.mjs:2:30: ERROR: Could not resolve "@vue/composition-api/dist/vue-composition-api.mjs"

          text: 'You can mark the path "@vue/composition-api/dist/vue-composition-api.mjs" as external to exclude it from the bundle, which will remove this error.'

Reopening because I actually still can't figure out what the correct path forward is.

Am I still required to manually include @vue/composition-api in my package.json if I'm using Pinia and Vue 2.7?
