無法導入matplotlib.pyplot

Question

我已經在CentOS 6.5中安裝了python 2.7.10。 然后我使用pip安裝了matplotlib。 但是，嘗試導入matplotlib.pyplot時出現以下錯誤。

import matplotlib.pyplot
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/site-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/site-packages/matplotlib/backends/__init__.py", line 32, in pylab_setup
    globals(),locals(),[backend_name],0)
  File "/usr/local/lib/python2.7/site-packages/matplotlib/backends/backend_tkagg.py", line 6, in <module>
    from six.moves import tkinter as Tk
  File "/usr/local/lib/python2.7/site-packages/six.py", line 203, in load_module
    mod = mod._resolve()
  File "/usr/local/lib/python2.7/site-packages/six.py", line 115, in _resolve
    return _import_module(self.mod)
  File "/usr/local/lib/python2.7/site-packages/six.py", line 82, in _import_module
    __import__(name)
  File "/usr/local/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

tkinter似乎已安裝。
“已安裝軟件包tkinter-2.6.6-66.el6_8.x86_64和最新版本”

我在python2.6 / lib-dynload中有_tkinter.so模塊，但是與python2.7 / lib-dynload中的tkinter沒有任何關系。

/usr/lib64/python2.6/lib-dynload/_tkinter.so
/usr/local/lib/python2.7/lib-tk/test/test_tkinter

另外，我在python中驗證了sys.path以獲得以下內容：

Python 2.7.10 (default, Jun  1 2017, 18:51:46)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-18)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> print '\n'.join(sys.path)

/usr/local/lib/python27.zip  
/usr/local/lib/python2.7  
/usr/local/lib/python2.7/plat-linux2  
/usr/local/lib/python2.7/lib-tk
/usr/local/lib/python2.7/lib-old  
/usr/local/lib/python2.7/lib-dynload  
/usr/local/lib/python2.7/site-packages

Answer 1

這可能是您的python庫路徑存在問題。 請檢查在安裝Tkinter的，並確保你有一個提供給您的Python解釋器。 您可以從tkinter導入其他內容嗎？

Answer 2

嘗試安裝tkinter，因為他們說“沒有名為_tkinter的模塊”。 您可以使用以下命令執行此操作：

sudo apt-get install python-tk
