Problem with Dependency Optimization in pnpm

Issue Overview

vitejs/vite#16293

There seems to be an issue with the optimization of the object-path package when using pnpm as the package manager, specifically in a polyrepo setup. This problem does not occur when using npm, indicating a potential discrepancy in how dependencies are handled between these package managers.

Steps to Reproduce

To observe the issue, follow these steps:

1. Navigate to the polyrepo directory using cd polyrepo.
2. Execute the command pnpm run dev:pnpm.
3. Upon opening the landing page, the following error is encountered:

   Uncaught SyntaxError: The requested module '/node_modules/.pnpm/object-path@0.11.8/node_modules/object-path/index.js?v=41e44650' does not provide an export named 'default' (at hello.tsx:2:8)
   

Expected Behavior with npm

For comparison, performing similar steps with npm does not result in this error:

1. In the polyrepo directory, run npm run dev:npm.
2. The landing page loads correctly, displaying the data without any issues.

Additional Context

Interestingly, when in a monorepo setup, the object-path package is optimized correctly using pnpm. For example:

• Navigate to monorepo/app folder.
• Run pnpm i followed by pnpm run dev.
• The landing page loads correctly, displaying the data as expected.

Additionally, the build process completes successfully on both package managers, which can be verified by running pnpm run build:pnpm and npm run build:npm, and then starting with the preview script.

This indicates that the issue might be specific to the development environment in polyrepo setups when using pnpm.
