💻 Code

https://github.com/jcreamer898/monorepo-examples/tree/main/pnpm-example

TL;DR file layout:

// monorepo-examples\pnpm-example\packages\pkg-a\index.ts
import { FontSizes, FontWeights, ITheme, IStyle } from "@fluentui/react";

// This expression's inferred type depends on @fluentui/merge-styles
export const something = { ... 

@fluentui/react is nested in /monorepo-examples/pnpm-example/node_modules/.pnpm/@fluentui+react

Adding a blank import to @fluentui/merge-styles in index.ts makes the problem go away

🙁 Actual behavior

src/index.ts:28:14 - error TS2742: The inferred type of 'personScopeListItemOverrides' cannot be named without a reference to '.pnpm/@fluentui+merge-styles@8.3.0/node_modules/@fluentui/merge-styles'. This is likely not portable. A type annotation is necessary.

🙂 Expected behavior

No error

Althought I don’t know why , "preserveSymlinks": true resolved my problems

We’re also running into this with https://github.com/saiichihashimoto/sanity-typed-schema-builder/issues/155. It’s unclear what should happen here, considering transitive type dependencies should work.
