Error message occurring while trying to install XFWM on Gentoo Linux


Hello there, so I did this command
Code:
emerge xfce-base/xfwm4
and then later on, I got a message saying

Code:
!!! The ebuild is selected to satisfy "dev-util/gbus-codegen" has unmet requirements.
- dev-util/gdbus-codegne-2.64.5::gentoo USE="" ABI_X86="(64)" PYTHON_SINGLE_TARGET="-python3_6 -python3_7 -python3_8"

The following REQUIRED_USE flag constraints are unsatisfied:
exactly-one-of ( python_single_target_python3_6 python_single_target_python3_7 python_single_target_python3_8 )

(dependency required by "xfce-base/xfconf-4.14.3::gentoo" [ebuild])
(dependency required by "xfce-base/xfwm4-4.14.5::gentoo" [ebuild])
(dependency required by "xfce-base/xfwm4" [argument])
Are there anyways to solve this problem?

Gentoo works with USE flags to determine which options a package should be compiled with. In this case the package dev-util/gbus-codegen (pulled in as a dependency of xfce-base/xfwm4) needs to know which ONE version of Python you want it compiled with.

To find out what version of python your system is currently using run eselect

Code:
$ eselect python show
You then need to tell your system to use this USE flag.

If you are new to Gentoo, I recommend bookmarking the Wiki. There is a lot of information that can be found there!
