Tkinter module not found on Ubuntu

Python 2.7.1+ (r271:86832, Apr 11 2011, 18:05:24)

on the other hand...

Python 3.2 (r32:88445, Mar 25 2011, 19:28:28) 
[GCC 4.5.2] on linux2

>>> 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 Do not edit Modules/Setup (it is out of date).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开发者_运维百科 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?

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.

---

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

That is with lowercase t.

---

In python 3 Tkinter renamed tkinter

---

Use the following command:

sudo apt-get install python3-tk

The following commands do not work:

sudo apt-get install python3-tkinter
sudo apt-get install python3-Tkinter
pip3 install Tkinter
pip3 install tkinter

---

sudo apt-get install python3-tk

---

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.

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

---

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.

---

this works for me:

from tkinter import *
root = Tk()
l = Label(root, text="Does it work")
l.pack()

---

I found this looking for a fix for python 3.5.

In my case I was building python from source, here is what I did to help fix:

Add the tkinter headers with and rebuild python

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

---

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.

---

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

---

requirement for tkinter:

python 3.6+

and go to shell write the test code like :

from tkinter import *

root = Tk()

root.mainloop()

---

For Ubuntu 20.04 this works for me.

sudo apt-get install python3.6-tk
