I am having this same issue but it seems nobody has an answer to this issue? However the module encodings is there under site-packages.

Hi, I am from ROS on Windows team. This issue most likely is caused by a extra python38.dll under c:\opt\ros\noetic\x64\bin\python38.dll. Removing it should fix the issue and we are working on removing this extra file in the next release.

This is what I am getting after removing the python38.dll

I:\catkin_ws>rospack depends1 mapping_drone [rospack] Error: the rosdep view is empty: call 'sudo rosdep init' and 'rosdep update'

This is the last 3 lines of trace on update.

File "c:\opt\ros\noetic\x64\lib\site-packages\rosdep2\installers.py", line 328, in __init__ self.sudo_command = 'sudo -H' if os.geteuid() != 0 else '' AttributeError: module 'os' has no attribute 'geteuid'

@Acoker251 A new release is out and I believe this issue was addressed. Can you retry again? Thanks!
