      # 步骤 1: 安装必要依赖
      - name: Install System Dependencies
        run: |
          sudo dpkg --add-architecture i386
          sudo apt-get update
          sudo apt-get install -y xvfb wine64 wine32 wine binutils
          sudo apt-get clean # 及时清理 apt 缓存节省硬盘空间

      # 步骤 2: 在后台持续运行 Xvfb
      - name: Start Xvfb
        run: |
          # 启动 X 虚拟屏幕并放到后台，供整个工作流期间的 Wine 使用
          Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1 &

      # 步骤 3: 下载 Python Windows 安装包
      - name: Download Python Installer
