Hello, Since I'm running into this on a private repository, I can provide the steps to set up a minimal project that demonstrates the issue.
🛠️ Minimal Reproduction Steps The core issue appears when using a pnpm-based monorepo configuration:
Initialize a pnpm workspace (monorepo):
Bash
pnpm init -w Create a simple TypeScript package:
Create a directory for the package (e.g., packages/example-package).
Add a package.json and a simple type file (e.g., src/index.ts) that exports a type:
TypeScript
// packages/example-package/src/index.ts export type SimpleType = { id: number; name: string; }; Create a service/application:
Create a directory for the service (e.g., apps/service).
Add a package.json that includes example-package as a dependency:
JSON
// apps/service/package.json (excerpt) "dependencies": { "@example/package": "workspace:*" } Install dependencies and try to use the type:
Run pnpm install at the monorepo root.
In the service, try to import and use the type:
TypeScript
// apps/service/src/main.ts import type { SimpleType } from '@example/package'; // ⬅️ This is where the error occurs
const myData: SimpleType = { id: 1, name: 'Test' }; // ... 🛑 The Error When trying to compile or run the service, the following TypeScript error is thrown for the import statement:
Cannot find module '@example/package' or its corresponding type declarations ts(2307)
This suggests the service cannot correctly resolve the types exported by the local package within the pnpm monorepo structure.
