在安装Anaconda后，使用ROS的Python工具如rospkg、rqt_graph等遇到ImportError。问题源于Anaconda默认Python版本与ROS所需Python2.7.x不匹配。解决方案包括注释掉.bashrc中Anaconda添加的路径或创建ROS专用的conda环境。参考相关文献可了解更多详情。

问题1

rosun出错 ImportError: No module named rospk
安装了anaconda后找不到 rospkg

一种解决办法：

ImportError: No module named rospkg

I did pip install rospkg since I have anaconda. It worked.

(as a side note, for some packages I also got “No module named Em”, for which I used pip install empy)

问题2

电脑安装Anaconda3，运行rosrun rqt_graph rqt_graph报错

Could not import "pyqt" bindings of qt_gui_cpp library - so C++ plugins will not be available:
