I took out the double space and it still doesn't fix it for me. I've tried updating all my dependencies but it makes not difference. I see that it is in the documentation so am perplexed as to why it is not working. I even tried taking it out of the each and it has the same error.

I did notice that the Travis build passed so it could just be something with my configuration. If that is the case then other people could be similarly affected so we need to make sure the configuration issues get corrected.
