我正在开发一个python和C ++项目，并希望生成一个全局的html文档。对于python部分，我已经设置了sphinx来生成文档。这就像一个魅力。
但现在有了C ++部分。 首先我通过pip安装了呼吸，然后跟着quick start guide。
为了简化测试，我创建了只有一个类的简单C ++项目。 我还用doxygen创建了所需的xml文件。
现在我希望sphinx生成文档。我发布了sphinx-quickstart一切都是默认的。之后，我将以下行添加到conf.py文件中：
extensions = ['breathe']
# -- Options for Breathe
breathe_projects = { "test": "/home/ubuntu/Downloads/testDocu/xml" }
breathe_default_project = "test"
我还将index.rst更改为：
.. Test documentation master file, created by
sphinx-quickstart on Wed Jul 19 09:18:10 2017.
You can adapt this file completely to your liking, but it should at least
contain the root `toctree` directive.
Welcome to Test's documentation!
================================
.. toctree::
:maxdepth: 2
:caption: Contents:
.. doxygenclass:: MyClass
:members:
Indices and tables
==================
* :ref:`genindex`
* :ref:`modindex`
* :ref:`search`
但是当我现在运行make html时，我收到以下错误消息：
Exception occurred: File "/usr/lib/python2.7/dist-packages/docutils/transforms/universal.py", line 290, in apply
txtnode.parent.replace(txtnode, nodes.Text(newtext)) AttributeError: 'NoneType' object has no attribute 'replace' The full traceback has been saved in /tmp/sphinx-err-fLAGKW.log, if you want to report the issue to the developers. Please also report this if it was a user error, so that a better error message can be provided next time. A bug report can be filed in the tracker at <https://github.com/sphinx-doc/sphinx/issues>. Thanks! make: *** [html] Error 1
这是一个知道错误还是我做错了什么？
