Solution

The error is generated because you are using the Python version 3.9 or above. The package that is causing error is:

backports.zoneinfo==0.2.1

To solve this error change the above line to:

backports.zoneinfo==0.2.1;python_version<"3.9"

Or, you can also use:

backports.zoneinfo;python_version<"3.9"

This will solve the error and your package will be installed successfully.
