I have some problems with tkinter. I want to use it with python 2.7.9 or python 3.4 with DEBIAN but it give me this error in both cases:

Python 3.4.3 (default, Dec  1 2017, 16:25:43) 
[GCC 4.9.2] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.4/tkinter/__init__.py", line 38, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
ImportError: No module named '_tkinter'

Can you give me some advice to resolve this? I already tried 

sudo apt-get install tk-dev

but

erle@erle-brain:~ $  sudo apt-get install tk-dev
[sudo] password for erle: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package tk-dev

I also see that maybe I have to install tcl and tk with this instructions but:

erle@erle-brain:~/build $ sudo apt-get install tcl8.5-dev libi2c-dev autoconf
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package tcl8.5-dev
E: Couldn't find any package by regex 'tcl8.5-dev'

Please help me :( I have to finish a University project and I need Tkinter.

In my version of Python 2 the module is called Tkinter (upper case initial T).

In my version of Python 3 the module is called tkinter (lower case initial t). For Python 3 I had to additionally install tk (sudo apt-get install python3-tk).

  • I tried to use Python 2.7 but when I write "import Tkinter" in the terminal the error is the same. and also when I try "sudo apt-get install python3-tk" this is the output: "Package python3-tk is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

    E: Package 'python3-tk' has no installation candidate "

  • The assumption is you are using Raspbian. Is that correct? You need to fully specify the environment you are using. – joan Dec 01 '17 at 20:16
  • You're right. I'm using Debian Jessie on raspberryPi3. – flavia13 Dec 01 '17 at 20:22
  • Using Debian rather than Raspbian is outside my experience. – joan Dec 01 '17 at 20:31

I solved the problem doing the apt-get update and apt-get upgrade, then doing sudo apt-get install python3-tk and import tkinter on the python terminal works. Now I have another issue but I will open a new topic. Thank you!!!!
