Cannot find python module rosdep2.rospack

edit

I'm currently doing the tutorial which is offered by ROS wiki. I've defined the beginner_tutorials package (as shown in the following page: ROS Tutorials - Creating Package).

When I try to run the following command on the terminal:

$ rospack depends1 beginner_tutorials

But I got the following error:

ModuleNotFoundError: No module named 'rosdep2'
ModuleNotFoundError: No module named 'rosdep2'
[rospack] Error: could not find python module 'rosdep2.rospack'. is rosdep up-to-date (at least 0.10.4)?

I installed rosdep via the following command and updated it:

$ sudo apt install python3-rosdep2
$ rosdep update

I then ran the same rospack command as before:

$ rospack depends1 beginner_tutorials

The following is the error message I receive:

could not find python module 'rosdep2.rospack', continuing without it
roscpp
std_msgs

I have read somewhere that removing Anaconda should fix the issue, but I'm trying to understand first why this is happening and secondly I don't want to remove Anaconda as I do quite some work on it!

All help would be greatly appreciated!
