### 2. Install System Dependencies for PDF Export (Optional)
> ⚠️ **Note**: If you need to use the PDF export function, please install system dependencies following the steps below. If you don't need PDF export, you can skip this step, and other system functions will not be affected.
> 💡 **Tip**: If using Docker deployment, no need to manually install these dependencies, the Docker image already contains all necessary system dependencies.
### 3. Install Dependencies
> If you skip step 2, the weasyprint library will fail to install, which is expected.
```bash
# Basic dependency installation
pip install -r requirements.txt
# uv version command (faster installation)
uv pip install -r requirements.txt
