[bug]: No import alias found in your tsconfig.json file.

Describe the bug

I've tried several approach and with different versions of React and Shadcn but I'm getting the same error no matter what I do.

With Tailwind v4 and React 19 (as per Tailwind v4 and React 19 #6585), I execute these commands:

pnpm create next-app@canary --tailwind --eslint --typescript --app --no-src-dir
cd my-app && pnpm dlx shadcn@canary init

I get this error message:

✔ Preflight checks.
✔ Verifying framework. Found Next.js.
✔ Validating Tailwind CSS config. Found v4.
✖ Validating import alias.

No import alias found in your tsconfig.json file.
Visit https://ui.shadcn.com/docs/installation/next to learn how to set an import alias.

Setting up a project with React 18 and the non-canary latest version of Shadcn produces the same error message.

Here is my tsconfig.json:

{
"compilerOptions": {
"target": "ES2017",
"lib": ["dom", "dom.iterable", "esnext"],
"allowJs": true,
"skipLibCheck": true,
"strict": true,
"noEmit": true,
"esModuleInterop": true,
"module": "esnext",
"moduleResolution": "bundler",
"resolveJsonModule": true,
"isolatedModules": true,
"jsx": "preserve",
"incremental": true,
"plugins": [
{
"name": "next"
}
],
"paths": {
"@/": ["./src/"]
}
},
"include": ["next-env.d.ts", "/*.ts", "/.tsx", ".next/types/**/.ts"],
"exclude": ["node_modules"]
}

I'm attempting to create an empty project with React (18 or 19), Tailwind, TypeScript, Tailwind, Shadcn.

I've tried all combos of "./src/", "src/", as well as using "pnpm dlx shadcn@latest init" and "npm install @radix-ui/react-slot", always with the same error.

I'm not a web developer so Claude, ChatGPT and DeepSeek have been going around in circles trying different approaches for some hours.

You've specified --no-src-dir when creating the Next app, but are then adding an alias path to ./src/ in your tsconfig.json.

Change the following in your tsconfig.json:

"paths": {
    "@/*": ["./*"]
}
