I have tried to install the module "Chatterbot 0.4.6", but it fails with the following error:
Exception:

What could be causing this to happen?
As correctly recommended by @Adryr83, the sudo command is often needed for linux platforms when installing Python packages with pip.
For example:
sudo pip install chatterbot
