When working with Python, you may come across the common error message “No module named _tkinter.” This error can be frustrating, especially for beginners, as it prohibits you from running certain applications or modules. However, there are ways to solve this issue and get back on track with your Python programming. In this article, we will discuss the causes of the error message and provide solutions to help you resolve it.
Cause of the “No module named _tkinter” Error
The “No module named _tkinter” error occurs when the _tkinter module is not installed or cannot be found in your Python environment. This module is a graphical user interface (GUI) toolkit that is included as a standard module in most Python installations. However, some distributions, such as the ones used in virtual environments, may not have it installed by default. Additionally, if you are using Python on a server or remote machine without a graphical interface, the _tkinter module may not be available.
Solutions
One solution to the “No module named _tkinter” error is to install the module manually. On Linux, you can install the module using your distribution’s package manager, such as apt-get or yum, by running the command:
sudo apt-get install python3-tk
On Windows and macOS, you can download and install the appropriate version of Python with the tkinter module included from the official Python website. Alternatively, you can install tkinter using pip, the Python package installer, by running the command:
pip install tkinter
If the above solutions do not work, you can also try running your Python program with a virtual environment that includes the _tkinter module. These virtual environments are isolated from your system’s Python installation and can be customized to meet the needs of your project.
The “No module named _tkinter” error may seem like a roadblock in your Python programming journey, but it can be easily resolved with the right tools and knowledge. By understanding the causes of the error and implementing the solutions that work best for your environment and project, you can continue to develop your skills and applications with confidence. Remember to always stay curious, learn from your mistakes, and don’t be afraid to ask for help when you need it.
What is “No module named _tkinter” error?
“No module named _tkinter” is a common error message encountered by Python users. The error typically occurs when running certain Python applications or scripts that utilize the module ‘_tkinter’. This module is used for creating graphical user interfaces (GUIs) and is a standard Python library for this purpose. The error indicates that the module is missing or not installed properly, which prevents Python from importing and using it properly.
What are the common causes of “No module named _tkinter” error?
The most common causes of this error are as follows:

To fix the “No module named _tkinter” error, users can try the following solutions:
- Installing the ‘_tkinter’ module by running the command ‘sudo apt-get install python3-tk’ on Linux or ‘python -m tkinter’ on Windows.
- Reinstalling Python with support for ‘_tkinter’, either by downloading an installer with ‘_tkinter’ support or compiling and building Python with ‘_tkinter’ support.
- Updating Python to the latest version that supports ‘_tkinter’, if applicable.
The “No module named _tkinter” error is a common issue encountered by Python users trying to use the ‘_tkinter’ module for GUI-related tasks. The error message indicates that the module is either missing or not installed properly, and several solutions are available to fix it. By understanding the common causes and solutions for the error, users can more easily resolve it and continue using Python and ‘_tkinter’ for their projects and applications.
How to Install or Update Tkinter?
If you’re encountering an error such as “No module named ‘_tkinter'” or “ModuleNotFoundError: No module named ‘tkinter'” in your Python3, it could be because you do not have Tkinter installed or it is outdated.
To install Tkinter, you can use pip, which is a package manager for Python. You can run the following command in your command prompt or terminal to install Tkinter:
However, you may encounter an error while trying to install Tkinter via pip. In this case, you may have to use alternative methods to install or update Tkinter. One alternative method is to use Anaconda, which is a data science platform that includes many Python packages out of the box. You can use the following command to install Tkinter using Anaconda:
Another alternative method for updating or installing Tkinter is by downloading and installing the latest version of Python that includes it.
Whichever method you choose, make sure to follow the instructions and installation guide carefully to successfully install Tkinter and avoid any errors.
Testing the Tkinter module after installation
The first step after installing the Tkinter module is to test whether it works or not. One can create a simple GUI application using the Tkinter module to ensure that it is installed correctly. Code a simple Tkinter window with a label and a button, and then try to run it.
If the code runs without any errors, then the module is installed correctly; otherwise, an error message will appear with the relevant information about the error. One common error message is “No module named ‘_tkinter'”, which indicates that the module is not installed or there’s an issue with the installation.
To resolve this issue, one can try installing Tkinter again using pip or updating the pip version. If the error persists, then consider installing alternative modules that can provide similar functionality as the Tkinter module.
Common Errors with Tkinter and their Solutions
Tkinter is not working with virtual environments
When trying to run Tkinter in a virtual environment, you may encounter an error. This happens because the system is not able to find the required libraries. To solve this error, you can install Tkinter in the operating system by running a command in the command prompt: sudo apt-get install python3-tk. Once it is installed, you can easily use it in your virtual environment by activating it first and then running the script.
Using Tkinter in Python 2 and 3
Tkinter supports both Python 2 and 3. However, there are some syntax differences between these two versions. For example, you use “tkinter” instead of “Tkinter” in Python 3. Another important difference is the module importing method. In Python 2, you can import the module using the “import Tkinter” statement. In Python 3, you need to use “import tkinter”.
Tkinter module not found in Python
If you get an error message saying “ModuleNotFoundError: No module named ‘_tkinter'” when trying to import Tkinter in Python, it means the module is not installed. To solve this problem, you need to install it first. You can install it by running the following command in the command prompt: sudo apt-get install python3-tk
Tkinter file is named improperly
It is important to give a proper file name to avoid naming conflicts and confusing your system. Make sure that you are not naming your file “tkinter.py” or “Tkinter.py” as these names conflict with the Tkinter module. Instead, choose a unique and descriptive name for your Tkinter file.
Best Practices and Tips for avoiding “No module named _tkinter” error
When using Tkinter, ‘No module named _tkinter’ error is a common issue that can occur in Python. To avoid this error, here are some best practices and tips:
1. Install Tkinter using pip:
To install Tkinter, run the following command in the command prompt:
pip install tkinter
This command will start downloading and installing the necessary files for Tkinter.
2. Check for system dependencies:
Make sure that you have all the necessary system dependencies installed before running your Python code. This can include certain libraries, packages, or even specific versions of Python.
3. Use a virtual environment:
If you’re still encountering issues with Tkinter after trying the solutions above, try running your Python script in a virtual environment. This will create an isolated environment that only contains the necessary dependencies for your code to run.
4. Try using a different GUI library:
If all else fails, consider using a different GUI library such as PyQt or wxPython. These libraries have similar functionality to Tkinter and may not have the same issues.
