## Troubleshooting

### npm/Node.js Issues

#### Python Not Found
If you get a "Python not found" error:

```bash
# Install Python 3.8+
# macOS with Homebrew:
brew install python

# Ubuntu/Debian:
sudo apt-get install python3

# Windows: Download from python.org
```

#### Permission Errors
```bash
# Check your YouTrack API token
npx youtrack-mcp-tonyzorin --info

# Verify your environment variables
echo $YOUTRACK_URL
echo $YOUTRACK_API_TOKEN
```

### Docker Issues

#### Container Won't Start
```bash
# Check Docker is running
docker --version

# Check container logs
docker run --rm \
  -e YOUTRACK_URL="https://your.youtrack.cloud" \
  -e YOUTRACK_API_TOKEN="your-token" \
  tonyzorin/youtrack-mcp:latest --version
```

#### Port Already in Use
```bash
# Use a different port
docker run --rm -p 8001:8000 \
  -e YOUTRACK_URL="https://your.youtrack.cloud" \
  -e YOUTRACK_API_TOKEN="your-token" \
  tonyzorin/youtrack-mcp:latest --transport http
```

#### GitHub Container Registry Authentication
```bash
# If you get pull errors from ghcr.io, you might need to authenticate
docker login ghcr.io

# Then try pulling again
docker pull ghcr.io/tonyzorin/youtrack-mcp:latest
```

### GitHub Packages Issues

#### npm Registry Configuration
```bash
# If @tonyzorin/youtrack-mcp is not found, configure the registry
npm config set @tonyzorin:registry https://npm.pkg.github.com

# You might need authentication for GitHub Packages npm
npm login --registry=https://npm.pkg.github.com
```

#### Package Not Found
If GitHub Packages npm shows "package not found":
- The package is published only on releases
- Check if a release has been created
- Fallback to npmjs.org version: `npm install -g youtrack-mcp-tonyzorin`

### Common Issues (Both Options)

#### Connection Issues
If you can't connect to YouTrack:

- Verify your YouTrack URL is correct
- Check that your API token has proper permissions
- Ensure your network allows connections to YouTrack
- Try testing the API token manually:
  ```bash
  curl -H "Authorization: Bearer your-token" \
       "https://your.youtrack.cloud/api/admin/projects"
  ```

## Which Option Should I Choose?

### Choose **npm/Node.js** if you:
- ✅ Already have Node.js installed
- ✅ Want faster startup times
- ✅ Prefer lighter resource usage
- ✅ Need to modify or debug the server

**Registry Options:**
- **npmjs.org** (recommended): `youtrack-mcp-tonyzorin` - Better discovery, wider usage
- **GitHub Packages**: `@tonyzorin/youtrack-mcp` - Integrated with GitHub, requires registry config

### Choose **Docker** if you:
- ✅ Want isolated, consistent environments
- ✅ Don't want to install Node.js/Python
- ✅ Are running in containerized infrastructure
- ✅ Want guaranteed dependency compatibility

**Registry Options:**
- **Docker Hub** (recommended): `tonyzorin/youtrack-mcp` - Faster, no auth required
- **GitHub Container Registry**: `ghcr.io/tonyzorin/youtrack-mcp` - Integrated with GitHub, may require auth
