To display information about Bokeh and Bokeh server configuration,
type ``bokeh info`` on the command line.

.. code-block:: sh

    bokeh info

This will print general information to standard output, such as Python and Bokeh versions:

.. code-block:: none

    Python version        :  3.12.3 | packaged by conda-forge | (main, Apr 15 2024, 18:38:13) [GCC 12.3.0]
    IPython version       :  8.19.0
    Tornado version       :  6.3.3
    NumPy version         :  2.0.0
    Bokeh version         :  3.5.1
    BokehJS static path   :  /opt/anaconda/envs/test/lib/python3.12/site-packages/bokeh/server/static
    node.js version       :  v20.12.2
    npm version           :  10.8.2
    jupyter_bokeh version :  (not installed)
    Operating system      :  Linux-5.15.0-86-generic-x86_64-with-glibc2.35

Sometimes it can be useful to get just paths to the BokehJS static files in order
to configure other servers or processes. To do this, use the ``--static`` option

.. code-block:: sh

    bokeh info --static

This will produce output like what is shown below:

.. code-block:: none

    /opt/anaconda/envs/test/lib/python3.12/site-packages/bokeh/server/static
