What is missing? How to solve this issue?
I've already reinstalled the packages using
sudo apt install python3-dbus
and
sudo apt-get install -y python-dbus
It looks like your issue might be that you are using a venv. python3-dbus does not play nicely with venv's.
You can try using --system-site-packages as suggested in https://stackoverflow.com/a/13367493/7721752.
Or use pydbus and vext.gi

You may need install pycocotools.
$ pip install pycocotools

ModuleNotFoundError: No module named 'zlib'
I've read several SO posts with the same error message, and have tried their solutions, including attempting to install zlib using homebrew, which fails, and updating my Xcode developer tools. I also installed pip earlier using python get-pip.py, and it said it installed successfully.
The reason I need pip is to install a package for use on python 2.7, but doing $ pip install "package-name" produces the same error as above. I have both Python 2 and 3 installed on my machine, if that helps. I'm kind of new to pip and using the command line in general, and I'm super confused; if anyone could help me out I'd really appreciate it.
This is the OP. I was able to fix the issue, and wanted to post my solution here in case it would help others.
Essentially I believe it occurred because Python2 is default on my machine, but pip is by default pointing to resources pertaining to Python3, or something like that. Doing pip2 --version instead provided the expected response.
I am trying to run:-
roslaunch turtlebot_gazebo turtlebot_world.launch
but I am getting following error

This worked for me
pip install catkin_pkg
On Arch Linux: In my case, I installed from an AUR package python2-catkin_pkg which installed the library at /usr/lib/python2.7/site-packages. So just do a symlink from /opt/ros/kinetic/lib/python2.7/site-packages to /usr/lib/python2.7/site-packages/catkin_pkg. So do this when you're in /usr/lib/python2.7/site-packages directory:
ln -s /usr/lib/python2.7/site-packages/catkin_pkg catkin_pkg
Probably because your python version is too high as it was in my case. Try to use the system default python first.
Go back to /usr/bin/python3 and use that as the default.
For those who have conda installed, here is the solution:
https://github.com/colcon/colcon-ros/issues/118#issuecomment-1355078266
You need to install catkin_pkg into the environment. I'm using conda and I had to install catkin_pkg, empy, and lark:
conda install -c conda-forge catkin_pkg empy lark

Can anyone please help me with this situation. Thanks in advance
I even tried pip install markupsafe but still I am unable to get ansible working
Ansible is based on python and there is a python module that's missing called markupsafe
install it via pip, you may need to escalate privileges
pip2 install -I markupsafe
pip2 for python 2.x
-I to ignore and reinstall package if it's already installed
I uninstalled pip and installed it again.
brew uninstall pip
brew doctor
brew install pip

As far as I understand the error is:
ImportError: No module named socketpool
How can I install this module or how to resolve the problem?
As Ifthikhan sugessted: Install it using a package manager such as apt-get and thereafter using pip you can install socketpool.
I had this problem when installing couchapp. I used pip to install it, and I thought it completed, but when I ran it I had the ImportError problem. Turns out the pip install didn't succeed and I first needed to:
apt-get install python-dev
Then when I did a
pip install couchapp
all of the dependencies were installed and couchapp ran without a problem.
