Answer 1

Your error is highlighting the issue -- there's no db object to import from jsondb for the call in __init__.py .

def __init__(self, name="bot", logging=True):
      from jsondb.db import Database
                  ^^ this doesn't exist

I found the source for the 'ChatterBot' module on GitHub and it appears that the 'jsondb' that the author is importing is not the one you'd get if you installed from pip . Instead, the author is expecting you to use his jsondb module that can be found on GitHub.

You can likely resolve this by uninstalling the jsondb that you retreived from pip:

pip uninstall jsondb

and installing the ChatterBot author's jsondb module:

pip install git+https://github.com/gunthercox/jsondb.git

You ran into this error because the ChatterBot author is assuming that you had his package named jsondb installed and did not include the dependency in a typical manner.
