Note that some packages may be out of date. You can always get the newest
nbsphinx release from PyPI (using
pip). If you want to try the latest development version, have a look at the section Contributing.
If you are using the
conda package manager (e.g. with Miniforge, Miniconda or Anaconda), you can install
nbsphinx from the conda-forge channel:
conda install -c conda-forge nbsphinx
You can of course also install
pip, Python’s own package manager:
python3 -m pip install nbsphinx
Depending on your Python installation, you may have to use
python instead of
python3. If you have installed the module already, you can use the
--upgrade flag to get the newest release.
There are more packages available. For an overview, see repology.
Some of the aforementioned packages will install some of these prerequisites automatically, some of the things may be already installed on your computer anyway.
Of course you’ll need Python, because both Sphinx and
nbsphinx are implemented in Python. There are many ways to get Python. If you don’t know which one is best for you, you can try Anaconda.
You’ll need Sphinx as well, because
nbsphinx is just a Sphinx extension and doesn’t do anything on its own.
If you use
conda, you can get Sphinx from the conda-forge channel:
conda install -c conda-forge sphinx
Alternatively, you can install it with
pip (see below):
python3 -m pip install Sphinx
Recent versions of Python already come with
pip pre-installed. If you don’t have it, you can install it manually.
The stand-alone program pandoc is used to convert Markdown content to something Sphinx can understand. You have to install this program separately, ideally with your package manager. If you are using
conda, you can install pandoc from the conda-forge channel:
conda install -c conda-forge pandoc
If that doesn’t work out for you, have a look at
pandoc’s installation instructions.
The use of
nbsphinx is temporary, but will likely stay that way for a long time, see issue #36.
Pygments Lexer for Syntax Highlighting#
To get proper syntax highlighting in code cells, you’ll need an appropriate Pygments lexer. This of course depends on the programming language of your Jupyter notebooks (more specifically, the
pygments_lexer metadata of your notebooks).
For example, if you use Python in your notebooks, you’ll have to have the
IPython package installed, e.g. with
conda install -c conda-forge ipython
python3 -m pip install IPython
If you are using Anaconda with the default channel and syntax highlighting in code cells doesn’t seem to work, you can try to install IPython from the
conda-forge channel or directly with
pip, or as a work-around, add
extensions in your
For details, see Anaconda issue #1430 and nbsphinx issue #24.
If you want to execute your notebooks during the Sphinx build process (see Controlling Notebook Execution), you need an appropriate Jupyter kernel installed.
For example, if you use Python, you should install the
ipykernel package, e.g. with
conda install -c conda-forge ipykernel
python3 -m pip install ipykernel
If you created your notebooks yourself with Jupyter, it’s very likely that you have the right kernel installed already.
If your automatic builds on https://readthedocs.org are failing due to an error like the one below, add
doc/environment.yml to resolve.
