Package Exports Resolution Issue with CSS Imports

[DmitrySharabin]

Description

Cursor IDE doesn't properly resolve package exports for CSS imports, particularly when working with locally linked packages. When trying to import a CSS file using the package's defined exports path, the IDE suggests creating a new file instead of resolving to the correct location.

Steps to Reproduce

1. Create two projects in the same parent directory:

   workspace/
   ├── my-project/        # Main project
   └── my-ui-lib/         # Local package
   

2. Set up the local package my-ui-lib with the following structure:

   my-ui-lib/
   ├── package.json
   ├── dist/
   │   └── styles/
   │       └── theme.css
   

3. In my-ui-lib/package.json, define exports:

   {
     "name": "my-ui-lib",
     "exports": {
       "./styles/*": "./dist/styles/*.css"
     }
   }
   

4. In your main project's (my-project/package.json):

   {
     "dependencies": {
       "my-ui-lib": "file:../my-ui-lib"
     }
   }
   

5. Create a CSS file in your main project:

   @import "my-ui-lib/styles/theme.css";
   

6. Try to command-click (or ctrl-click) the import path

Current Behavior

The IDE suggests creating a new file at my-ui-lib/styles/theme.css instead of resolving to the actual file location at my-ui-lib/dist/styles/theme.css.

Expected Behavior

The IDE should resolve the import to my-ui-lib/dist/styles/theme.css based on the package exports mapping in the package.json.

Environment

• OS: darwin 24.4.0
• Cursor Version: 0.49.4

Additional Context

• Both projects must be in the same parent directory for the local package linking to work
• The file exists at the correct location (node_modules/my-ui-lib/dist/styles/theme.css)
• The package exports mapping is correctly defined in the package.json
• This appears to be specific to CSS imports and locally linked packages
