Tips--解决安装matplotlib无法使用pyplot的问题

问题描述

在安装matplolib的python2版本之后，发现在导入matplolib的时候是成功的：

import matplolib

但是在引入其中的pyplot包时是失败的：

import matplolib.pyplot as plt

报错信息为：

Traceback (most recent call last):
  File "", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/matplotlib/pyplot.py", line 115, in <module>
    _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()
  File "/usr/local/lib/python2.7/dist-packages/matplotlib/backends/__init__.py", line 63, in pylab_setup

    mod = mod._resolve()
  File "/usr/local/lib/python2.7/dist-packages/six.py", line 115, in _resolve
    return _import_module(self.mod)
  File "/usr/local/lib/python2.7/dist-packages/six.py", line 82, in _import_module
    __import__(name)
  File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 42, in <module>
    raise ImportError, str(msg) + ', please install the python-tk package'
ImportError: No module named _tkinter, please install the python-tk package

这是由于缺少python-tk的原因

解决方法

安装python-tk即可，注意是apt安装而不是pip进行安装：
Python2安装命令：

sudo apt-get install python-tk

Python3安装命令：

sudo apt-get install python3-tk
