Tkinter Module Import Error: Solutions and Prevention

If you encounter the error "ModuleNotFoundError: No module named 'Tkinter'" when attempting to import the Tkinter module in Python, this issue arises due to the module not being installed on your system.

Installation

To resolve this, you can install the Tkinter module using your package manager based on your operating system:

• Ubuntu/Debian

sudo apt-get install python3-tk

• CentOS/Fedora/Red Hat

sudo dnf install python3-tkinter

Platform-Specific Considerations

When specifying the package to install, include the Python version you're using. For example:

sudo apt-get install python3.7-tk

sudo dnf install python3-tkinter-3.6.6-1.fc28.x86_64

Importing Tkinter

After installation, you can import the Tkinter module correctly:

• Python 3:

import tkinter as tk

• Python 2:

import Tkinter as tk

Version Flexibility

If you intend to support both Python 2 and 3, you can use the following code to import Tkinter based on the Python interpreter version:

import sys

if sys.version_info[0] == 3:
    import tkinter as tk
else:
    import Tkinter as tk
