✅ SOLUTION: How to Fix the Errors

The Two Errors You're Getting:

Error 1: uvicorn is not recognized

Cause: You're using uvicorn directly instead of python -m uvicorn

Error 2: Could not import module "main"

Cause: You're running from the wrong directory (project root instead of backend)

---

✅ THE CORRECT WAY (Copy & Paste This):

Option 1: Use the Batch File (Easiest)

Just double-click: start_backend.bat in the project root

Option 2: Manual Steps

Step 1: Open PowerShell or Command Prompt

Step 2: Navigate to backend directory:

cd "D:\COmplete project\demo\backend"

Step 3: Run this EXACT command:

python -m uvicorn main:app --reload --port 8000

IMPORTANT:

• ✅ Use python -m uvicorn (NOT just uvicorn)
• ✅ Make sure you're in the backend directory
• ✅ The command should show: INFO: Uvicorn running on http://127.0.0.1:8000

---

🔍 How to Verify You're in the Right Place:

# Check current directory
pwd

# Should show: D:\COmplete project\demo\backend

# List files - you should see main.py
dir

# Should show: main.py, database.py, etc.

📋 Complete Setup Checklist:

1. ✅ Navigate to backend:

   cd backend

2. ✅ Create database (if not done):

   python create_database.py

3. ✅ Initialize data (if not done):

   python init_db.py

4. ✅ Start server (USE THIS EXACT COMMAND):

   python -m uvicorn main:app --reload --port 8000

---

✅ Test It Works:

After starting, open browser:

• http://localhost:8000/health → Should show {"status": "healthy"}
• http://localhost:8000/docs → Should show Swagger UI

---

🎯 Quick Reference Card:

✅ CORRECT:
cd backend
python -m uvicorn main:app --reload --port 8000

❌ WRONG:
uvicorn main:app --reload --port 8000
python -m uvicorn main:app --reload --port 8000  (from project root)
