Can't import tkinter after installing Python 3 with pyenv

I'm having trouble importing tkinter

after installing Python version 3.4.2 with pyenv

. My Python system is version 2.7.6. I am using Ubuntu 14.04. For the following example script t.py

:

import _tkinter

print ("Hello")

I get:

$ pyenv global system
$ python --version
Python 2.7.6
$ python t.py
Hello
$ pyenv global 3.4.2
$ python --version
Python 3.4.2
$ python t.py
Traceback (most recent call last):
  File "t.py", line 3, in <module>
    import _tkinter
ImportError: No module named '_tkinter'
    Traceback (most recent call last):
      File "t.py", line 3, in <module>
        import _tkinter
    ImportError: No module named '_tkinter'

Note that pyenv

Python 3.4.2 is installed in ~/.pyenv/versions/3.4.2/

.

This issue has now been resolved using the approach described in this post :



  • Remove Python 3.4.2: first pyenv uninstall 3.4.2

    , then
  • Execute sudo apt-get install tk-dev

  • And reinstall Python 3.4.2: pyenv install 3.4.2

Change your code to:

import tkinter


Documentation link :

In most cases tkinter is all you really need, but a number of additional modules are also available. The Tk interface is located in a binary module named _tkinter. This module contains a low-level interface to Tk and should never be used directly by application programmers. This is usually a shared library (or DLL), but in some cases it can be statically linked to the Python interpreter.
