解决ros安装中的报错“
catkin_make失败 ImportError: “from catkin_pkg.package import parse_package” failed: No module named ‘catkin_pkg’"
笔者是在Nvidia Jetson Xavier NX板子上学习ROS的,Ubuntu18.04的版本,在按照ROS教程http://wiki.ros.org/cn/ROS/Tutorials/CreatingPackage中输入catkin_make报错了,查了资料后觉得大概是python3缺包的愿意,于是输入
pip3 install catkin_pkg -i https://pypi.douban.com/simple 安装catkin_pkg的包
直接输入pip3 install catkin_pkg会报错。
