I have installed tkinter package but the default Python (which is version 2.7) on CentOS 7 still complains that this package doesn't exist.
sudo rpm --query centos-release
centos-release-7-5.1804.el7.centos.2.x86_64
sudo yum install tkinter
...
Package tkinter-2.7.5-69.el7_5.x86_64 already installed and latest version
python -m tkinter
/usr/bin/python: No module named tkinter
python
Python 2.7.5 (default, Jul 13 2018, 13:06:57)
