[trim21]

Vue version

3.2.41

Link to minimal reproduction

https://github.com/trim21/vue-compile-core-missing-deps

there is a vue type shim

declare module '*.vue' {
  import type { DefineComponent } from "vue";
  const component: DefineComponent<{}, {}, any>;
  export default component;
}

Steps to reproduce

git clone https://github.com/trim21/vue-compile-core-missing-deps
cd vue-compile-core-missing-deps
npm i
npx tsc --noEmit

What is expected?

tsc type checking ok

What is actually happening?

System Info

doesn't matter

Any additional comments?

This is fixed with @babel/types in deps.

It's by design I think. If you need TypeScript support then install it by yourself.

You can enable skipLibCheck in tsconfig

I added PR #10533 solving issue. It seems to come back here a lot (already 3 issues: #5625, #8917, and this) and technically if compiler-core depends on library it should have it in dependencies (as in my PR).

Requiring from users adding dev dependencies of some of their dependencies creates confusion, and after some time you end up with a lot of dependencies where you don't know anymore if it's needed or was added to fix some missing transitive dep.
