Shadcn UI Initialization Error: Issues with tailwind.config.ts, Missing src Folder, and index.css

[willslax]

I am encountering a persistent issue when initializing Shadcn UI in a Next.js 15 project with TypeScript. Despite following standard setup procedures, including generating the project with npx create-next-app@latest, I receive errors indicating that:

1. Shadcn UI is looking for tailwind.config.js instead of tailwind.config.ts, even though the TypeScript configuration is present and works correctly with Tailwind.

2. It demands a src folder and an index.css file, while my project uses a global.css file, and I opted out of creating a src directory during setup.

These issues are unexpected because tutorials and recent videos using the same setup process do not encounter these errors. My environment includes Node.js 18+, and all dependencies are up to date.
