Import pyplot, RuntimeError: Unable to create tklinter dlopen module file

Question

I used pyenv to install pypy in windows bash, then use pip to install matplotlib, but when importing pyplot I got RunTimeError

 In [1]: import matplotlib.pyplot as plt --------------------------------------------------------------------------- RuntimeError Traceback (most recent call last) <ipython-input-1-eff513f636fd> in <module>() ----> 1 import matplotlib.pyplot as plt /home/zjshao/.pyenv/versions/pypy-5.3.1/site-packages/matplotlib/pyplot.pyc in <module>() 112 113 from matplotlib.backends import pylab_setup --> 114 _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup() 115 116 _IP_REGISTERED = None /home/zjshao/.pyenv/versions/pypy-5.3.1/site-packages/matplotlib/backends/__init__.pyc in pylab_setup() 30 # imports. 0 means only perform absolute imports. 31 backend_mod = __import__(backend_name, ---> 32 globals(),locals(),[backend_name],0) 33 34 # Things we pull in from all backends /home/zjshao/.pyenv/versions/pypy-5.3.1/site-packages/matplotlib/backends/backend_tkagg.pyc in <module>() 11 12 # Paint image to Tk photo blitter extension ---> 13 import matplotlib.backends.tkagg as tkagg 14 15 from matplotlib.backends.backend_agg import FigureCanvasAgg /home/zjshao/.pyenv/versions/pypy-5.3.1/site-packages/matplotlib/backends/tkagg.pyc in <module>() 7 import numpy as np 8 ----> 9 from matplotlib.backends import _tkagg 10 11 def blit(photoimage, aggimage, bbox=None, colormode=1): RuntimeError: Cannot dlopen tkinter module file In [2]: 

So what could be the problem and how to solve this problem?

Any suggestions would be appreciated!

Maybe something is wrong with your python installation. The best ways are to remove python and reinstall.

I suggest you install python from Anaconda . This is the "next click" of the installer (amazing for Windows), which sets the python path environment variable and has a pre-installed package, including "mathplotlib".
