ubuntu 16.4 上的 tkinter 导入错误 [英] tkinter import error on ubuntu 16.4

问题描述

我试图运行一个使用乌龟画树的代码.代码没有问题，因为我在windows 10上运行成功，但是在ubuntu上，遇到如下错误:

I tried to run a code which use turtle to draw a tree. There is no problem with code because I ran it on Windows 10 successfully, but on Ubuntu, the following error was encountered:

mosharraf@mmh:~$ cd Desktop
mosharraf@mmh:~/Desktop$ python3 Tree.py
Traceback (most recent call last):
  File "Tree.py", line 6, in <module>
    import turtle 
  File "/usr/local/lib/python3.6/turtle.py", line 107, in <module>
    import tkinter as TK
  File "/usr/local/lib/python3.6/tkinter/__init__.py", line 36, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
ModuleNotFoundError: No module named '_tkinter'
mosharraf@mmh:~/Desktop$

然后我尝试安装 tkinter 但我失败了.

Then I tried to install tkinter but I failed.

mosharraf@mmh:~$ sudo apt-get install python3-tk
[sudo] password for mosharraf:

python3-tk is already the newest version (3.5.1-1).

mosharraf@mmh:~$

之后，我检查了目录中的 tkinter 并找到了它.

Afterwards, I checked for the tkinter in the directories and found it.

mosharraf@mmh:/usr/local/lib/python3.6$ cd tkinter
mosharraf@mmh:/usr/local/lib/python3.6/tkinter$ ls

tkinter 位于您在上面看到的目录中，但我无法导入它.我尝试了几种方法，例如

tkinter is in the directories as you can see above, but I can't import it. I tried several ways like

import tkinter

import tkinter as tk

from tkinter import *

等

请注意，我在 python 2.7 中运行代码并成功运行.我还在 Windows 10、Python 3.6 上运行了代码.但在 Ubuntu 中，它导致了问题.

Note that I ran the code in python 2.7 and it ran successfully. I also ran the code on Windows 10, Python 3.6. But in Ubuntu, it's causing the problem.

推荐答案

在你的帖子底部你说:

请注意，我在 python 2.7 中运行代码并成功运行.

Note that I ran the code in python 2.7 and it ran successfully.

当您从 Python 2 导入 Tkinter 时，您必须说:

When you import Tkinter from Python 2 you must say:

导入 Tkinter

当您从 Python 3 导入 Tkinter 时，您必须说:

When you import Tkinter from Python 3 you must say:

导入 tkinter

当我知道我的脚本将从多个版本的 Python 运行时，我用于 Tkinter 的片段如下:

A snippet I use for Tkinter when I know that my script is going to be ran from multiple versions of Python is below:

import sys

py_version = int(sys.version[0])

# If the python version is lower than 3, use Python 2 import
if py_version < 3:
    import Tkinter

# Otherwise use Python 3 import 
else:
    import tkinter

如果以上没有解决您的问题:

我在您的一条错误消息中看到它说

IF THE ABOVE DID NOT FIX YOUR PROBLEM:

I see that in one of your error messages it says

python3-tk 已经是最新版本(3.5.1-1).

但错误消息还说您的 Python 版本是 3.6.

But the error message also says that your Python version is 3.6.

尝试使用:sudo apt-get install python3.6-tk
