Describe the bug

I created a sample small project to play work workspaces. But it appeared Yarn doesn't download libraries (dependencies) despite showing successful output.

To reproduce

1. Unzip attached zip file.
2. Be sure you are using node@^20 and yarn@4.1.1 (or try on other versions if you don't have these)
3. on the src folder from the attached zip file run: yarn install
4. observe the node_modules folder in the src/ folder

Expected - there is a src/node_modules folder and there is a src/pack_a/node_modules folder to contain specific version of rtrim (1.0.1)
Actual: there is no any node_modules folder created ever.

Here is the console output on my run:

user@system ~/src $ yarn install
