首先，

import tkinter

然后報(bào)錯(cuò)如下：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'tkinter'

但是我已經(jīng)sudo apt-get install python3-tk了啊
為什么還是找不到模塊。目前用的python3
然后我在matplotlib下畫圖，也是報(bào)這個(gè)錯(cuò)。

import matplotlib.pyplot as plt

報(bào)錯(cuò)如下：

 import matplotlib.pyplot as plt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/dist-packages/matplotlib/pyplot.py", line 115, in <module>
    _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()
  File "/usr/local/lib/python3.6/dist-packages/matplotlib/backends/__init__.py", line 62, in pylab_setup
    [backend_name], 0)
  File "/usr/local/lib/python3.6/dist-packages/matplotlib/backends/backend_tkagg.py", line 4, in <module>
    from . import tkagg  # Paint image to Tk photo blitter extension.
  File "/usr/local/lib/python3.6/dist-packages/matplotlib/backends/tkagg.py", line 5, in <module>
    from six.moves import tkinter as Tk
  File "/usr/lib/python3/dist-packages/six.py", line 92, in __get__
    result = self._resolve()
  File "/usr/lib/python3/dist-packages/six.py", line 115, in _resolve
    return _import_module(self.mod)
  File "/usr/lib/python3/dist-packages/six.py", line 82, in _import_module
    __import__(name)
ModuleNotFoundError: No module named 'tkinter'

總之就是找不到tkinter，我也裝了tkinter，而且什么tcl/tk也裝了，就是找不到，求解決，浪費(fèi)了很久時(shí)間了。

我早已用apt-get install python3-tk，但是還是找不到tkinter
