When I was installing ROS noetic, I typed sudo rosdep init, an ModuleNotFoundError occured:
(base) tongji@tongji-Nuvo-8108GC-Series:~$ sudo rosdep init [sudo] password for tongji: Traceback (most recent call last): File "/usr/local/bin/rosdep", line 5, in <module> from fixed_rosdep.main import rosdep_main File "/usr/local/lib/python3.8/dist-packages/fixed_rosdep/__init__.py", line 45, in <module> from .lookup import RosdepDefinition, RosdepView, RosdepLookup, \ File "/usr/local/lib/python3.8/dist-packages/fixed_rosdep/lookup.py", line 41, in <module> from .rospkg_loader import RosPkgLoader File "/usr/local/lib/python3.8/dist-packages/fixed_rosdep/rospkg_loader.py", line 39, in <module> import catkin_pkg.package ModuleNotFoundError: No module named 'catkin_pkg.package'
Then I tried installing catkin_pkg, but the error remains.

How can I solve this problem?
