(Pdb)

Problem description

I'm trying to build the documentation, following the instructions in the Contributing to pandas docs. Unfortunately, I hit a Python debugger along the way, causing the build to fail.

Do you have any advice on how to get past this issue?

Expected Output

No errors when building the documentation when following the documentation. Ideally no warnings either.

Output of pd.show_versions()

you need to: source activate pandas_dev

I guess it would help to be even more explicit in the doc instructions.

@jreback My bad, that was one of the steps, just forgot to include it in the write-up 😬. I've updated my original post to reflect that. The result is still the same, unfortunately.

you didn't do these steps: http://pandas.pydata.org/pandas-docs/stable/contributing.html#requirements

as an aside I think there is an issue to add: lxml to requirements_all.txt (and should add pyarrow, feather as well.

lxml is already included in requirements_all.txt. As are sphinx, ipython, and nbconvert and nbformat (via nbsphinx).

I did miss the optional requirements as I had (incorrectly) assumed that requirements_all.txt contained all mandatory and optional requirements.

I've updated my original post to reflect the changes. I also added the Making changes step of running python manage.py develop as well. I'm still experiencing the same issue, unfortunately.

@mattayes We just had the same question on gitter, and there is was ipykernel that was missing. Can you install that one and see if it then works?

I'm working on updating the contributing docs now.

Awesome, installing ipykernel did the trick, thank you! And thanks for improving the docs, I appreciate it!

All - I was able to re-setup code semantic-fabric from scratch over the weekend, and I identified a number of gaps.
I have identified lots of issues for which I have solutions, including the ipykernel example.
Where are we documenting the build? I feel that this needs to be in the readme file under "build" section.
