MoveIt：入门无法配置柳絮工作区

问题描述

ubuntu 20.04 LTS 玫瑰诺言

我正在执行步骤 here，但在 catkin 工作区配置中出现错误。

    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：我刚开始使用 Linux 和 ROS

解决方法

我做了以下操作，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

moveit ros ros
