Sphinx自动文档在readthedocs上出现问题：ImportError: No module named _tkinter。

我想要建立关于 https://readthedocs.org/ 的文档。

对于任何导入matplotlib的文件，我都看不到docstrings。

当我查看构建日志时，我发现from matplotlib import pyplot as plt失败了，并显示以下消息：

/home/docs/checkouts/readthedocs.org/user_builds/artemis-ml/checkouts/latest/docs/source/plotting.rst:67: WARNING: autodoc: failed to import function u'dbplot' from module u'artemis.plotting.db_plotting'; the following exception was raised:

ImportError: No module named _tkinter

我已经在readthedocs的“管理员>高级设置”页面中指定了以下要求：
  • 项目应该在virtualenv中构建
  • 项目应该使用包含matplotlib的requirements.txt文件进行构建。您可以从上面的消息中看到它已经被安装了，只是显然安装不正确。
有人遇到过这种情况并知道如何解决吗？
由于这是关于readthedocs的问题，所以Tkinter: "Python may not be configured for Tk"中的答案对此无效。

MERose提供的解决方案可能是最好的，但如果不起作用，这里还有另一种解决方法：

你可以通过使用“agg”后端让sphinx使用import matplotlib，而不需要tkinter，只需打开<project root>/docs/source/conf.py并插入以下行：

import matplotlib
matplotlib.use('agg')

在此结束。

导致导入错误的包需要在您的计算机上安装！我尝试在另一台电脑上创建文档，但该电脑上并未安装我的项目中包含的所有软件包，这当然会引发导入错误。

也许我只是在这里指出了显而易见的问题，但我花了相当长的时间才弄清楚这是问题所在。
