Tkinter module not found on Ubuntu

Python 2.7.1+ (r271:86832, Apr 11 2011, 18:05:24) 
[GCC 4.5.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter
>>>

on the other hand...

Python 3.2 (r32:88445, Mar 25 2011, 19:28:28) 
[GCC 4.5.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named Tkinter

I checked synaptic, Tkinter is installed. Then I found this--

If it fails with "No module named _tkinter", your Python configuration needs to be modified to include this module (which is an extension module implemented in C). Do not edit Modules/Setup (it is out of date). You may have to install Tcl and Tk (when using RPM, install the -devel RPMs as well) and/or edit the setup.py script to point to the right locations where Tcl/Tk is installed. If you install Tcl/Tk in the default locations, simply rerunning "make" should build the _tkinter extension.

I am guessing that tkinter is still associated with the old python in my pc. How do I change that so python3 can use tkinter?

The answer to your question is that Tkinter is renamed to tkinter in python3.

That is with lowercase t.

If you are using Ubuntu 18.04 along with Python 3.6, then pip or pip3 won't help. You need to install tkinter using following command:

sudo apt-get install python3-tk

Adding solution for CentOs 7 (python 3.6.x)

yum install python36-tkinter

I had tried about every version possible, hopefully this helps out others.

I had the same problem. I tried to use:

sudo apt-get install python3-tk

It gave an error stating blt(>=2.4z-7) is not present and is not installable.

I went here and manually installed it. (For Ubuntu 14.04)

Then I used apt again and it worked.

I concluded that python3.4 in Ubuntu didn't come with the .so file required to carry on installation. And blt was required to download it.

Adding the solution that I faced with python 3.4 on Fedora 21. Hope this will help those facing a similar issue.

Any of these commands will install tkinter:

sudo yum install python3-tkinter
OR
sudo dnf install python3-tkinter

What worked for me in Ubuntu was actually just:

sudo apt-get install python3-tk

For python 3.6:

sudo apt-get install python3.6-tk

I didn't read anywhere, I simply tried it, as onteria_'s method didn't seem to work for me.

Add the tkinter headers with and rebuild python

sudo apt-get install tk8.6-dev
sudo make

Since you mention synaptic I think you're on Ubuntu. You probably need to run update-python-modules to update your Tkinter module for Python 3.

EDIT: Running update-python-modules

First, make sure you have python-support installed:

sudo apt-get install python-support

Then, run update-python-modules with the -a option to rebuild all the modules:

sudo update-python-modules -a

I cannot guarantee all your modules will build though, since there are some API changes between Python 2 and Python 3.
