python3運行ros方法 No module named 'rospkg'

我們安裝的ros後,其一般的庫文件均基於python2,但是當某個項目必須要用python3時,就會出現如下錯誤:

Traceback (most recent call last):
  File "/home/jetbot/arm_all/xArm-Python-SDK-master/example/wrapper/common/xarm_publish.py", line 16, in <module>
    import rospy
  File "/opt/ros/kinetic/lib/python2.7/dist-packages/rospy/__init__.py", line 49, in <module>
    from .client import spin, myargv, init_node, \
  File "/opt/ros/kinetic/lib/python2.7/dist-packages/rospy/client.py", line 52, in <module>
    import roslib
  File "/opt/ros/kinetic/lib/python2.7/dist-packages/roslib/__init__.py", line 50, in <module>
    from roslib.launcher import load_manifest
  File "/opt/ros/kinetic/lib/python2.7/dist-packages/roslib/launcher.py", line 42, in <module>
    import rospkg
ImportError: No module named 'rospkg'

即python3中無rospy,解決辦法如下:

$ sudo apt-get install -y python3-pip
$ sudo pip3 install rospkg
$ sudo pip3 install netifaces
$ sudo pip3 install defusedxml

安裝完成後,即可python3來運行ros節點了.
