Common issues and solutions when using Docyrus UI web components.

## Verify your versions

Make sure your environment meets or exceeds these minimum versions.

| Dependency | Minimum Version |
|---|---|
| React | 19 |
| Next.js | 16 |
| Tailwind CSS | 4.0 |
| Node.js | 18 |
| Radix UI | 1.4.0 |

## Registry not found

If you see a "registry not found" error when installing components, make sure you've added the Docyrus registry to your `components.json` file. The registry URL should point to `https://ui.docy.app/r`. Without this entry, neither the shadcn CLI nor the Docyrus CLI will know where to fetch components from.

## Components not resolving after installation

After installing a component, your imports should point to the local file path where the component was placed — not to an NPM package. If your IDE shows unresolved imports, check that the component files were actually written to disk and that your TypeScript path aliases match the install location.

## Tailwind CSS v4 classes not applying

Tailwind CSS v4 uses a CSS-based configuration system. If component styles aren't applying, make sure your CSS entry file includes a `@source` directive that covers the directory where Docyrus UI components are installed. Without this, Tailwind's compiler won't scan those files for utility classes.

## Dark mode not working

Docyrus UI components use CSS custom properties (CSS variables) for theming. Dark mode relies on these variables being defined in your global stylesheet. If dark mode isn't working, verify that your theme variables are set up correctly for both light and dark color schemes.

## Motion library version conflicts

Some Docyrus UI components use the Motion library for animations. If you see runtime errors related to motion or framer-motion, make sure you're using a compatible version. Docyrus UI targets Motion v12 and above.
