无法在ubuntu 20.04上运行catkin构建

Question

我有Ubuntu20.04，我刚刚安装了ROS，，noetic，和catkin。

但是每次我做catkin build时，我都有一个错误列表，不能继续。你们能帮我解决这个问题吗。

Traceback (most recent call last):

    from catkin_tools.commands.catkin import main

、apt和pip3版本的catkin_tools都被打破了。解决办法是像这样安装：

sudo pip3安装git+https://github.com/catkin/catkin_tools.git
