CAUTION最后没有成功。建议不要使用这种方式，建议使用 docker 部署 ubuntu 20.04 来完成。下文作为笔记保留。
安装
参考 ROS 官网文档：https://wiki.ros.org/noetic/Installation/Source
安装完成之后，使用这一行命令就能引用 ros1 了
source ~/ros_catkin_ws/install_isolated/setup.bash
或者用 colcon 构建的
source ~/ros_catkin_ws/install/setup.bash
当出现错误时，尝试修正中，可以使用 catkin_build_isolated <pkg name> 避免繁琐的所有包构建
遇到的问题
rosdep update 报错，网络问题
原因：网络被墙，考虑使用 rosdepc 或者开 VPN 再尝试
vcs import --input noetic-desktop.rosinstall ./src 命令会很慢，且报错
原因：依然是网络被墙，方法同上

qt_gui_cpp: The detected Python minor version is not compatible
The detected Python minor version is not compatible with the Python minor version which was used when Shiboken was built.
Consider building shiboken with FORCE_LIMITED_API set to ‘1’, so that only the Python major version matters.
原因：python版本不满足造成的，可以指定 python 工具完成

安装相关依赖 python-sip-dev
sudo apt-get install sip-dev pyqt5-dev python-sip-dev pyqt5-dev-tools

解决：跳过这个包的构建。。。

不能直接用 pip，注意给 sudo 权限
