Python not configured for Tk

Question

I am using Ubuntu 13.10 and Python 3.3.4 using pyenv. I have no problem using other modules. When I enter python console and write

import tkinter 

It outputs

Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/serdar/.pyenv/versions/3.3.4/lib/python3.3/tkinter/__init__.py", line 40, in <module> import _tkinter # If this fails your Python may not be configured for Tk ImportError: No module named '_tkinter' 

I already installed python3-tk and tk-devel.

Answer 1

You need to have the Tk development files/headers available during pyenv install.

On Ubuntu (15.04) the following should provide them: sudo apt-get install tk-dev.

After this, pyenv install 3.4.3 (or pyenv install 2.7.10 etc) should pick it up and have support for Tk.

(Reference issue in pyenv)

Answer 2

This is a guide for Mac users,

1. Uninstall your python version. For example: pyenv uninstall 3.7.2
2. Install TK: brew install tcl-tk
3. Follow the post install steps and config tk:

export LDFLAGS="-L/usr/local/opt/tcl-tk/lib" export CPPFLAGS="-I/usr/local/opt/tcl-tk/include" export PATH=$PATH:/usr/local/opt/tcl-tk/bin 

4. Reload your terminal session and make sure all settings above are correctly set
5. Install python: pyenv install 3.7.2

The TK should work now
