## 🐛 Troubleshooting & Debugging

### Common Issues dan Solutions:

1. **Port Already in Use:**
```bash
# Cari process yang menggunakan port
lsof -i :8501

# Kill process
kill -9 $(lsof -t -i:8501)

# Atau gunakan port lain
streamlit_launcher --port 8502
```

2. **Module Import Errors:**
```bash
# Check Python path
python -c "import sys; print(sys.path)"

# Reinstall package
pip uninstall streamlit-launcher
pip install --no-cache-dir streamlit-launcher
```

3. **Permission Issues:**
```bash
# Gunakan virtual environment
python -m venv myenv
source myenv/bin/activate

# Atau install untuk user
pip install --user streamlit-launcher
```

4. **Performance Issues:**
```bash
# Enable caching
@st.cache_data
def load_data():
    return pd.read_csv('large_file.csv')

# Use lighter data types
df = df.astype({col: 'category' for col in categorical_columns})
```

### Debug Mode:

```bash
# Enable detailed logging
streamlit-launcher --log-level debug

# Atau set environment variable
export STREAMLIT_LOG_LEVEL=debug
export STREAMLIT_DEBUG=true

# Debug specific component
import streamlit as st
st.write(st.session_state)  # Print session state
```

## 🚀 Deployment & Production
