install error in wsl2

[csj3684]

Hi.

I wanna use rosbag to csv, so tried to install it by README.
but I have some errors.

• (py38_64) @@@@@ :~/catkin_ws$ rosdep install -r --ignore-src --from-paths src
• WARNING: ROS_PYTHON_VERSION is unset. Defaulting to 3
• ERROR: the following packages/stacks could not have their rosdep keys resolved
• to system dependencies (ROS distro is not set. Make sure ROS_DISTRO environment variable is set, or use --rosdistro option - to specify the distro, e.g. --rosdistro indigo):
• rosbag_to_csv: Cannot locate rosdep definition for [rospy]
• Continuing to install resolvable dependencies...
• executing command [sudo -H apt-get install pyqt4-dev-tools]
• Reading package lists... Done
• Building dependency tree
• Reading state information... Done
• E: Unable to locate package pyqt4-dev-tools
• ERROR: the following rosdeps failed to install
• apt: command [sudo -H apt-get install pyqt4-dev-tools] failed
• apt: Failed to detect successful installation of [pyqt4-dev-tools]

I think I resolved 'ROS distro is not set' by add '--rosdistro=ROS_DISTRO', but still have two errors.

• rosbag_to_csv: Cannot locate rosdep definition for [rospy]
• E: Unable to locate package pyqt4-dev-tools

and I installed python-rospy in person by 'sudo apt install python-rospy' (of course, I did apt upgrade and update) but it also have error

• Package python-rospy is not available, but is referred to by another package.
• This may mean that the package is missing, has been obsoleted, or
• is only available from another source
• However the following packages replace it:
• python3-rospy
• E: Package 'python-rospy' has no installation candidate

And I installed python3-rospy but I stll have the same errors.

• rosbag_to_csv: Cannot locate rosdep definition for [rospy]

and when it comes to pyqt4-dev-tools, I have a following error.

• E: Unable to locate package pyqt4-dev-tools

What do I do ??

Thank you.

I'm running it on WSL2,

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.2 LTS
Release: 20.04
Codename: focal

python 3.8 (64bit)

I have the same errors with python 2.7 (64bit)

[csj3684]

I just resolved all things. I think I should've run with python 2.

but another issue comes.

I did run and convert it and it said "Finish Conver" with pop up. but in the path ~/.ros, No csv file.

Anything to know ??

thank you.
