ubuntu 20.04 LTS ros noetic

我正在按照此处的步骤操作，但 catkin 工作区配置出现错误。

    Traceback (most recent call last):
  File "/usr/bin/catkin", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 3254, in <module>
    def _initialize_master_working_set():
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 3237, in _call_aside
    f(*args, **kwargs)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 3266, in _initialize_master_working_set
    working_set = WorkingSet._build_master()
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 584, in _build_master
    ws.require(__requires__)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 901, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 787, in resolve
    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'osrf-pycommon>0.1.1' distribution was not found and is required by catkin-tools

PS：我刚开始Linux和ROS

我做了以下，现在看起来构建过程已经开始

sudo apt-get install python3

pip3 install osrf-pycommon>0.1.1
