Tkinter not running on updated python

Question

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
./configure
make
sudo make install

• Dougie: Is tkinter installed? What does python3 -m tkinter give you?
• Milliways: Your problem is probably caused by so I updated it to 3.7.4. How?
• tlfong01: @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.
• Tom Boddaert: @Milliways Thank you, I have updated the post to elaborate.
• Tom Boddaert: @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.

Answer 1

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
>>>tkinter._test()

• Tom Boddaert: 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.
• Daniel: Did you try uninstalling it, then reinstalling.
• Tom Boddaert: Yes both tkinter and raspian
• Daniel: 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

Answer 2

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.

• Tom Boddaert: Sorry, I missed the 3, I did run "python3 -m tkinter" and got an error
