Hi @DevDengChao.
can you try to delete your pnpm-locl.yaml + node_modules folder + pnpm install ?
Second: Do you have a package manager version inside your package.json, like: packages field missing or empty

[DevDengChao]

1. delete pnpm-lock.yaml
2. delete node_modules dir
3. pnpm install
4. ./node_modules/.bin/nuxt upgrade
5. choose dedupe when upgrading
6. fail with same error message

There is no package manager version specified in package.json
