Linux下:ModuleNotFoundError: No module named ‘tkinter‘

centos 7下运行带窗口的程序时报如下错误

[root@heartnet Desktop]# python3 inside_test.py 
Traceback (most recent call last):
  File "inside_test.py", line 1, in
    from tkinter import *
ModuleNotFoundError: No module named 'tkinter'

解决办法:
[root@heartnet Desktop]# yum install python3-tkinter.x86_64 

输入上述指令安装python的tk,重新运行程序即可解决.
