运行roscore命令报错

运行roscore命令报错如下：
Traceback (most recent call last):
File "/opt/ros/noetic/lib/python3/dist-packages/roslaunch/init.py", line 347, in main

import netifaces
ModuleNotFoundError: No module named 'netifaces'
然后我又使用pip install netifaces，系统提示Requirement already satisfied: netifaces in /usr/lib/python3/dist-packages (0.10.4)
请问接下来怎么办？ -
问题已解决，通过重新安装netifaces即可
pip uninstall netifaces
pip install netifaces
