Hi @nalancer08 I don't have a Mac to test with but I'll see what I can do to resolve this. One thing I just noticed is that there have been some updates to the ruamel.yaml library since version 0.15, one of which seems to include Python wheels (which may fix some of the c-related errors you are seeing in your output).

Want to try running the following and let me know if it installs?

pip install ruamel.yaml --upgrade

This should install the latest version of ruamel.yaml. It looks like I need to update the version that is pinned in the chatterbot-corpus package: https://github.com/gunthercox/chatterbot-corpus/blob/master/requirements.txt

How about python 3?

Thank you so much for everyone, I fixed compiling direct with

python setup.py build
python setup.py install

But, with PIP I didnt make it works

@nalancer08 I'm glad your issue was resolved. I am going to make changes to switch to a different Python YAML library to hopefully fix and prevent issues like this in the future.
