So, I'm trying to use a project, that uses tkinter on my Raspberry Pi but I have an issue. I needed an updated version of Python, so I updated it to 3.7.4, however, when I try to import tkinter, it gives me the error message ModuleNotFoundError: No module named '_tkinter'. Tkinter also gives the message If this fails, your Python may not be configured for Tk. Other modules import as usual. How can I configure Python to use Tk? Thank you, in advance, for any help.

python3 -m tkinter gives the same error message as trying to import it. I tried sudo apt-get install python-tk and sudo apt-get install python3-tk but it says it's already the latest version and doesn't do anything. I then uninstalled and reinstalled tkinter but that didn't help.

I updated Python by running these commands (I have wiped the system and done it again, but same issue):

cd ~
wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz
tar -zxvf Python-3.7.4.tgz
cd Python-3.7.4
sudo make install

    Is tkinter installed? What does python3 -m tkinter give you? – Dougie Oct 5 '19 at 18:58
  • Your problem is probably caused by so I updated it to 3.7.4. How? – Milliways Oct 6 '19 at 0:29
  • @Tom Boddaert, I am using Rpi4B buster release 2019sep26 Thonny 3.2 python 3.7.3 (/usr/bin/python3). I tried this: >>> import tkinter returns >>>. Your problem is NOT specific to tkinter. PS - I have not installed tkinter beforehand. – tlfong01 Oct 6 '19 at 1:00
  • @Milliways Thank you, I have updated the post to elaborate. – Tom Boddaert Oct 6 '19 at 8:57
  • @tlfong01 Thank you for the suggestion but can you please elaborate on what you mean by it's not specific to tkinter, all other modules that don't use tkinter, that I have tried, work. – Tom Boddaert Oct 7 '19 at 11:49

Check to see if it is installed use the terminal as Dougie stated in the comments.

If it's not installed type in the terminal
sudo apt-get install python3-tk

Testing in python shell
>>>import tkinter

  • Thank you for the suggestion but it just says that it's already the latest version and doesn't do anything but"python3 -m tkinter" produces the same error as trying to import it. – Tom Boddaert Oct 5 '19 at 21:59
  • Did you try uninstalling it, then reinstalling. – Daniel Oct 12 '19 at 21:06
  • Yes both tkinter and raspian – Tom Boddaert Oct 14 '19 at 6:52
  • Check to see if it's placing the library in the right folder. In Terminal cd /usr/local/lib/python3.7 Then list the files ls – Daniel Oct 19 '19 at 20:19

python -m tkinter quite correctly reports No module named tkinter because the Python2 version is Tkinter

python -m Tkinter should work!

There is no need to install tkinter, because it should be included in python3.

  • Sorry, I missed the 3, I did run "python3 -m tkinter" and got an error – Tom Boddaert Oct 6 '19 at 8:50
