从matplotlib.backends导入_tkagg ImportError:无法导入名称_tkagg

问题描述

尝试运行此示例来测试matplotlib如何与Tkinter一起工作时，我出现错误:

While trying to run this example to test how matplotlib works with Tkinter, I am getting the error:

(env)fieldsofgold@fieldsofgold-VirtualBox:~/new$ python test.py
Traceback (most recent call last):
  File "test.py", line 7, in <module>
    from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
  File "/home/fieldsofgold/new/env/local/lib/python2.7/site-packages/matplotlib/backends/backend_tkagg.py", line 13, in <module>
    import matplotlib.backends.tkagg as tkagg
  File "/home/fieldsofgold/new/env/local/lib/python2.7/site-packages/matplotlib/backends/tkagg.py", line 7, in <module>
    from matplotlib.backends import _tkagg
ImportError: cannot import name _tkagg

使用此处提供的解决方案，我尝试卸载matplotlib并使用以下命令安装tk和tk-dev软件包:

Using the solution provided here, I've tried to uninstall matplotlib and install the tk and tk-dev packages by using these commands :

sudo apt-get install tk8.5
sudo apt-get install tk-dev

，然后通过pip install matplotlib重新安装matplotlib但我仍然遇到相同的错误.任何帮助，将不胜感激.我在VirtualBox上使用Ubuntu 14.04，并在virtualenv环境中工作.非常感谢.

and then re-installing matplotlib again by pip install matplotlibbut I am still getting the same error. Any help would be appreciated. I am using Ubuntu 14.04 on VirtualBox and working inside a virtualenv environment.Thanks so much.

推荐答案

我刚刚遇到了这个问题(Ubuntu 15.10，但想法相同)，并通过以下方式解决了问题:

I just ran into this (Ubuntu 15.10 but same idea) and fixed it by:

sudo apt-get install tk-dev
pip uninstall -y matplotlib
pip --no-cache-dir install -U matplotlib

我认为第三步很关键；如果允许缓存，则pip似乎只是在使用先前构建的matplotlib安装.

I think the third step was the critical one; if the cache is permitted then pip appeared to be just using the previously-built installation of matplotlib.

您也可以手动删除以前构建的matplotlib；在Ubuntu上，它位于~/.cache/pip中的某个位置. (很遗憾，我找不到pip清除其缓存的方法.)

You can also manually remove the previously-built matplotlib; on Ubuntu it lives in ~/.cache/pip somewhere. (I couldn't find a way for pip to clean up its cache unfortunately.)
