ImportError: No module named '_tkinter' 解决办法

问题描述： 

Traceback (most recent call last):
  File "/usr/lib/python3.5/tkinter/__init__.py", line 36, in <module>
    import _tkinter
ImportError: No module named '_tkinter'

During handling of the above exception, another exception occurred:

    raise ImportError(str(msg) + ', please install the python3-tk package')
ImportError: No module named '_tkinter', please install the python3-tk package

 环境描述：

Ubuntu 16.04

Python 3.5.2

原因分析： 

根本不是tkinter没有安装，或者被正确安装完成，而是没有被正确的配置好。

解决办法1（懒人版）：

import matplotlib
matplotlib.use('agg')
import matplotlib.pyplot as plt

解决办法2： 

在终端执行一下命令

sudo apt-get update（如果不更新很有可能找不到tkinter）

sudo apt-get install python3-tk

 

注：也有说要卸载python后安装相关依赖，再重新编译python，以上发放不行的话百度新的方法重新试试。
