如何解决 import matplotlib.pyplot as plt 错误？

Question

我无法让我的 matplotlib 库正常工作。我在虚拟环境中运行它，并且安装了 numpy 和 matplotlib。我先打开我的虚拟环境，激活python，然后我进入，

import matplotlib 

一切顺利，但我进入了，

import matplotlib.pyplot as plt

我得到了错误，

    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

我尝试了许多不同的解决方案，但均无济于事。可能是什么问题呢？

使用下面提到的命令：

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

这对我有用。希望对你有帮助。
