如何通过 Nbsphinx 使用 Travis CI 和 Jupyter Notebooks

我正在尝试在 github 存储库中使用 nbsphinx 和 travis 以及 Jupyter 笔记本。

存储库设置：

.
├── _docs
|   ├── config.py # I added nbsphinx extension here
|   ├── including.rst # File with .. include :: ../projects/testingjupyter.ipynb
|   └── index.rst # basically just toctree with "including" among other titles
├── _projects
|   └── testingjupyter.ipynb
├── tests
├── travis.yml
└── requirements.txt

travis.yml：

language: python
python:
     - "2.7.12"
     - "3.5"
     - "3.5"
     - "nightly"

install: 
    - pip install -r requirements.txt
    - sudo apt-get install pandoc

script:
    - py.test tests/
    - travis-sphinx --source ./docs build

after_success:
    - travis-sphinx --branches=master,Develop deploy

要求.txt：

sphinx-rtd-theme==0.2.4
Sphinx==1.5.3
travis-sphinx==1.4.3
flask==0.12
jupyter
nbconvert
pandoc
nbsphinx
IPython
ipykernel

travis-sphinx尝试生成时，出现以下错误：意外的缩进

testingjupyter.ipynb ：
