I need help with a problem

I need help with a problem. That's not pinia bug. But I'm asking for your help

But I have registered @vue/composition-api

vue@2.6.14
pinia@2.0.5
@vue/composition-api@1.4.1

This is a quirk of the composition API in Vue2. See the Troubleshooting section in the following release for fixes: https://github.com/vuejs/composition-api/releases/tag/v1.3.0

We had a similar problem when one lib used an older version of vue-demi, so when we upgraded to Pinia@2 there were constant conflicts in resolution. If you're in a similar situation and using Vite then the following lines in your config under resolve.alias should fix it (as noted in the above link):

alias: [
  { find: /^@vue\/composition-api$/, replacement: '@vue/composition-api/dist/vue-composition-api.mjs' },
  { find: '@vue/composition-api/dist/vue-composition-api.esm.js', replacement: '@vue/composition-api/dist/vue-composition-api.mjs' },
  // your other aliases here
]
