Error building documentation (harea_step)

Hi all,

trying to build and install bokeh documentation locally, I get the following error, that I have not been able to solve:

Sphinx error:

harea_step is new, and only currently exists on development branch. You will either need to:

  • build and install a development version of the library, to build the latest development docs, or
  • check the repo out to a release tag, e.g. 3.1.0, corresponding to the version you have installed
