nandastone/vue-tsc-conflicting-global-types

Monorepo setup with package-a importing package-b, with both being built in library mode, and emitting types via vue-tsc.

Both package-a and package-b would eventually be consumed by a service.

pnpm i`
cd packages/package-a
pnpm build
cd ../package-b
pnpm build

Result:

> pnpm build

> package-b@1.0.0 build /Test/vite-vue-monorepo/packages/package-b
> vite build && pnpm build-types

Found 1 error in src/ComponentB.vue:2

 ELIFECYCLE  Command failed with exit code 2.
 ELIFECYCLE  Command failed with exit code 1.

Review the built packages/package-a/dist/types/ComponentA.vue.d.ts to see:

declare global {
  type __VLS_IntrinsicElements = __VLS_PickNotAny<
    import("vue/jsx-runtime").JSX.IntrinsicElements,
    __VLS_PickNotAny<globalThis.JSX.IntrinsicElements, Record<string, any>>
  >;
  // ... etc
}

Trying to build package-b is attempting to emit .d.ts with the same global type definitions, when they already exist from package-a.
