Rasa Core version: N/A

@akelad I didn't exactly solve the issue. I abandoned Windows and started developing on Linux instead.

This will work perfectly if you are using python version 3.5

[parasnigam1]

downgrade to python version 3.5, that's what i did and it got installed smoothly.

[Krogsager]

It turns out I needed to install a c compiler.
I just run apt-get update && apt-get install build-essential
Then I can pip install rasa_core and nlu.
