Ubuntu20.04中使用ROS运行usb_cam报错
我先利用小鱼的网站下载了ros-noetic然后编译usb_cam均可通过,然后在catkin_ws下运行如下命令
source devel/setup.bash
roslaunch usb_cam usb_cam-test.launch
报错,错误内容
... logging to /home/cmj/.ros/log/72349a50-5515-11ee-8f86-6b52ac0cda18/roslaunch-cmj-virtual-machine-50738.log

RLException: Invalid roslaunch XML syntax: syntax error: line 1, column 0

launch文件我没有修改过,直接运行的usb_cam那个包的内容,然后为此我还重新开了一个虚拟机跑了一遍还是报这个错误。
这个错误我在网上都没有找到,请问有没有靓仔帮我一下,感激不尽。
