我在此链接 (https://github.com/pyqtgraph/pyqtgraph/issues/1220) 中找到了解决方案。

以下安装后，PyQtGraph 示例代码开始工作：

sudo apt-get install -y libxkbcommon-x11-0 x11-utils
sudo apt-get install --no-install-recommends -y libyaml-dev libegl1-mesa libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-randr0 libxcb-render-util0 libxcb-xinerama0
