报错如下
Traceback (most recent call last):
File “/opt/ros/foxy/share/ament_cmake_core/cmake/core/package_xml_2_cmake.py”, line 21, in
from catkin_pkg.package import parse_package_string
ModuleNotFoundError: No module named ‘catkin_pkg’
观察发现为python文件
主要是因为前几天安装了miniconda，所以丢了些东西
安装如下：pip install catkin_pkg
