🔍 Analysis

The root cause is clear from the error trace:

Next.js package not found

This typically happens when Turbopack can't resolve the Next.js installation in your project.

---

✅ Solutions

1. Clean Install (Most Common Fix)

# Remove node_modules and lock files
rm -rf node_modules
rm -rf .next
rm package-lock.json  # or yarn.lock / pnpm-lock.yaml

# Reinstall
npm install

2. Check Next.js Version

Your error shows Next.js version: 0.0.0 - this indicates a broken installation.

# Verify Next.js is installed
npm ls next

# If missing or broken, reinstall
npm install next@latest

3. Turbopack Canary Mismatch

You're using Turbopack v16.1.0-canary.19 - canary versions can have compatibility issues.

# Use stable version instead
npm install next@latest

Or if you need canary:

npm install next@canary

4. Check package.json

Ensure next is in your dependencies:

{
  "dependencies": {
    "next": "^14.x.x"  // or your target version
  }
}

5. Clear Turbopack Cache

rm -rf .next
rm -rf node_modules/.cache
npm run dev

---

🔧 If Still Not Working

Try disabling Turbopack temporarily:

# Instead of
next dev --turbo

# Use
next dev

Hope this helps! Let me know if the issue persists. 🚀
