ModuleNotFoundError: No module named 'catkin_pkg'

遇到报错：
ModuleNotFoundError: No module named 'catkin_pkg'
execute_process(D:/ProgramData/Anaconda3/python.exe
执行程序为什么会指向conda下的python版本，而没有用为ros2安装的默认python3.8.3版本呢？
在官方humble-windows安装流程中，catkin_pkg已安装于python3.8.3下了：
python -m pip install -U catkin_pkg cryptography empy importlib-metadata lark==1.1.1 lxml matplotlib netifaces numpy opencv-python PyQt5 pillow psutil pycairo pydot pyparsing==2.4.7 pyyaml rosdistro
