RDFLib entry failed to resolve

[renyuneyun]

After #74 , I attempted to use rdflib instead. After installing dependencies, the build still errors out:

✘ [ERROR] Failed to resolve entry for package "rdflib". The package may have incorrect main/module/exports specified in its package.json. [plugin vite:dep-pre-bundle]

  This error came from the "onResolve" callback registered here:

  The plugin "vite:dep-pre-bundle" was triggered by this import

      5 │ } from 'rdflib';
        ╵        ~~~~~~~~

I have installed @ldflex/rdflib and rdflib.

MRE also see https://github.com/renyuneyun/minimal-reproduction/tree/master/ldflex-getting-started, and uncomment line 7 (and comment out line 6) of src/App.vue to see this error.
