type ``bokeh info`` on the command line. The locations will be printed

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      :  2.7.11
    IPython version     :  4.0.1
    Bokeh version       :  0.11.0
    BokehJS static path :  /opt/anaconda/lib/python3.4/site-packages/bokeh/server/static

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/lib/python3.4/site-packages/bokeh/server/static
