Question

我已经设置了一个虚拟环境，当我尝试在其上运行matplotlib时，出现以下错误：

Traceback (most recent call last):
  File "/Users/sumeet/PycharmProjects/VISM/test2.py", line 2, in <module>
    import matplotlib.pyplot as plt
  File "/Users/sumeet/tensorflow/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/sumeet/tensorflow/lib/python2.7/site-packages/matplotlib/backends/__init__.py", line 62, in pylab_setup
    [backend_name], 0)
  File "/Users/sumeet/tensorflow/lib/python2.7/site-packages/matplotlib/backends/backend_tkagg.py", line 4, in <module>
    from . import tkagg  # Paint image to Tk photo blitter extension.
  File "/Users/sumeet/tensorflow/lib/python2.7/site-packages/matplotlib/backends/tkagg.py", line 5, in <module>
    from six.moves import tkinter as Tk
  File "/usr/local/Cellar/python/2.7.14_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/six.py", line 203, in load_module
    mod = mod._resolve()
  File "/usr/local/Cellar/python/2.7.14_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/six.py", line 115, in _resolve
    return _import_module(self.mod)
  File "/usr/local/Cellar/python/2.7.14_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/six.py", line 82, in _import_module
    __import__(name)
  File "/usr/local/Cellar/python/2.7.14_2/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

根据我的理解，我需要

set激活脚本中的环境变量
或我可以symlink tkinter将文件夹发送到virtualenv python2.7。

我已按照此处的步骤操作：TKinter in a Virtualenv，但我仍然收到错误。

我遵循的步骤是：

对于virtualenv / bin / activate，我补充道 TK_LIBRARY=/usr/lib/python2.7/lib-tk:/usr/lib/python2.7/site-packages/PIL:/usr/lib TKPATH=/usr/lib/python2.7/lib-tk:/usr/lib/python2.7/site-packages/PIL:/usr/lib TCL_LIBRARY=/usr/lib export TCL_LIBRARY TK_LIBRARY TKPATH
在virtualenv / lib / python2.7中，我跑了，ln -s /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/_tkinter.so

请注意，当我使用系统Python作为PyCharm的解释器时，matplotlib工作正常，这让我觉得Tkinter在我的系统某处可用，但我无法从我的虚拟环境中调用它。

上面的链接似乎适用于Ubuntu。我想知道是否有人知道什么是Mac的类似版本。

谢谢！

如果您不特定于在虚拟环境中使用tkinter，则可以使用以下代码行：

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

我希望这可以解决问题。

虚拟环境中的Tkinter（PyCharm / Mac OS 10.13.4）
