Ubuntu 18.04 ROS Melodic
Python 3.10.2 (when i run python --version)
Description: I was following the official tutorial from ROS wiki on installing ROS Melodic but I having a problem when i tried to init rosdep.
Installation of rosdep was not a problem. the result is as follows:
sudo apt install python-rosdep Reading package lists... Done Building dependency tree Reading state information... Done python-rosdep is already the newest version (0.21.0-1). 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
However, the initialisation of rosdep return this:
sudo rosdep init Traceback (most recent call last): File "/usr/bin/rosdep", line 6, in <module> from pkg_resources import load_entry_point File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 77, in <module> __import__('pkg_resources.extern.packaging.requirements') File "/usr/lib/python3/dist-packages/pkg_resources/_vendor/packaging/requirements.py", line 9, in <module> from pkg_resources.extern.pyparsing import stringStart, stringEnd, originalTextFor, ParseException File "<frozen importlib._bootstrap>", line 1027, in _find_and_load File "<frozen importlib._bootstrap>", line 1006, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 672, in _load_unlocked File "<frozen importlib._bootstrap>", line 632, in _load_backward_compatible File "/usr/lib/python3/dist-packages/pkg_resources/extern/__init__.py", line 43, in load_module __import__(extant) File "/usr/lib/python3/dist-packages/pkg_resources/_vendor/pyparsing.py", line 943, in <module> collections.MutableMapping.register(ParseResults) AttributeError: module 'collections' has no attribute 'MutableMapping'
Hence, I suspect it is due to python version. I hope I could get a second opinion on this.
