## 🐛 Troubleshooting

### Common Issues

#### 1. Command not found: vira

**Solution:**
```bash
# Check if installed
pipx list | grep vira-cli

pipx reinstall vira-cli

# Or add to PATH
export PATH="$PATH:$HOME/.local/bin"
```

#### 2. API Key Error

**Error:**
```
❌ No API key found. Run: vira --config
```

**Solution:**
```bash
# Method 1: Interactive setup
vira --config

# Method 2: Direct set
vira --set-api-key

# Method 3: Environment variable
export GEMINI_API_KEY="your_key_here"
```

#### 3. Clipboard Error

**Error:**
```
⚠️ Could not copy to clipboard
```

**Solution:**
```bash
# Linux X11
sudo apt-get install xclip

# Linux Wayland
sudo apt-get install wl-clipboard

# macOS (should work by default)
# Windows (should work by default)
```

#### 4. Interactive Commands Stuck

**Problem:** Commands like `npm install` hang without accepting input.

**Solution:** Already fixed in version 2.1.0. Update:
```bash
pipx upgrade vira-cli
```

#### 5. Import Errors

```
ModuleNotFoundError: No module named 'prompt_toolkit'
```

**Solution:**
```bash
pip install prompt-toolkit rich pyperclip python-dotenv google-generativeai
```

#### 6. Permission Denied

## ❓ FAQ

### General Questions

**Q: Is Vira CLI free?**  
A: Yes, Vira CLI is open-source (MIT License). However, you need a Google Gemini API key, which has a free tier.

**Q: Does it work offline?**  
A: No, Vira requires internet connection to communicate with Gemini API.

**Q: Which operating systems are supported?**  
A: Linux, macOS, and Windows. Commands are optimized for each OS.

**Q: Can I use it in scripts?**  
A: Yes, use `--run` flag for non-interactive execution:
```bash
vira list files --run > output.txt
```

### Usage Questions

**Q: How do I save my favorite commands?**  
A: Use the alias system:
```bash
vira --set-alias mybackup="tar -czf backup.tar.gz ."
```

**Q: Can it execute commands automatically?**  
A: Yes, use `--run` flag, but be careful:
```bash
vira delete old logs --run  # No confirmation!
```

**Q: How to switch languages?**  
A: Run `vira --set-language` and choose your language.

**Q: Does it support multiple commands?**  
A: Currently one command per query. Use aliases for command chains.

### Technical Questions

**Q: Which AI model should I use?**  
A: 
- `gemini-2.5-flash`: Fast, good for simple commands (default)
- `gemini-2.5-pro`: Best quality, slower, for complex queries

**Q: How is my data stored?**  
A: All data stored locally in `~/.vira-cli/`:
- `config.ini`: Settings and API key
- `chat_history.txt`: Query history
- `vira.log`: Debug logs (if enabled)

**Q: Is my API key secure?**  
A: API key is stored with 600 permissions (owner read/write only). Never share your config file.

**Q: Can I use my own AI model?**  
A: Currently only Gemini models are supported. Custom model support is planned.

### Troubleshooting

**Q: Commands are slow?**  
A: 
1. Check internet connection
2. Switch to faster model (gemini-2.5-flash)
3. Use alias for frequent commands

**Q: Getting wrong commands?**  
A:
1. Be more specific in your query
2. Switch to pro model for better accuracy
3. Report issue with examples

**Q: History not working?**  
A: Check if `~/.vira-cli/chat_history.txt` is writable:
```bash
ls -la ~/.vira-cli/
chmod 600 ~/.vira-cli/chat_history.txt
```
