如何解決 import matplotlib.pyplot as plt 錯誤？

Question

我無法讓我的 matplotlib 庫正常工作。 我在虛擬環境中運行它，並且安裝了 numpy 和 matplotlib。 我先打開我的虛擬環境，激活python，然后我進入，

import matplotlib 

一切順利，但我進入，

import matplotlib.pyplot as plt

我得到錯誤，

    Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/kendallreid/.virtualenvs/cv/lib/python2.7/site-packages/matplotlib/pyplot.py", line 115, in <module>
    _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()
  File "/Users/kendallreid/.virtualenvs/cv/lib/python2.7/site-packages/matplotlib/backends/__init__.py", line 32, in pylab_setup
    globals(),locals(),[backend_name],0)

    from six.moves import tkinter as Tk
  File "/Users/kendallreid/.virtualenvs/cv/lib/python2.7/site-packages/six.py", line 203, in load_module
    mod = mod._resolve()
  File "/Users/kendallreid/.virtualenvs/cv/lib/python2.7/site-packages/six.py", line 115, in _resolve
    return _import_module(self.mod)
  File "/Users/kendallreid/.virtualenvs/cv/lib/python2.7/site-packages/six.py", line 82, in _import_module
    __import__(name)
  File "/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk/Tkinter.py", line 39, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
ImportError: No module named _tkinter

我嘗試了許多不同的解決方案都無濟於事。 可能是什么問題呢？

使用下面提到的命令：

import matplotlib
matplotlib.use(‘TkAgg’)
import matplotlib.pyplot as plt

這對我有用。 我希望它有所幫助。
