ROS "rqt_graph“命令不适用于windows 10

Question

我已经在我的windows 10机器上安装了ROS1 NOETIC，但是我无法运行"rosrun rqt_graph rqt_graph“命令来查看图表。降至误差以下

Traceback (most recent call last):
  File "c:\opt\ros\noetic\x64\lib\site-packages\rqt_graph\ros_graph.py", line 284, in _update_rosgraph
    self._refresh_rosgraph()

解决办法很简单。由于我在windows 10中安装ROS时使用了巧克力，所以我可以使用同样的方法安装"graphviz“，如下所示

choco install graphviz
