Hello,

I get this error trying to run juicer:

I have read that it could be because my installation of matplotlib does not have gtk support compiled, but I installed python with anaconda... any suggestions ?

Thanks!

Yeah, that problem is not related to juicer itself, and happens because your matplotlib installation doesn't have that C extension installed. In systems such as Ubuntu / Debian it would be as simple as running apt-get install python-gtk2-dev. I have close to zero experience with Mac Os and know even less about Anaconda. Maybe something like this thread might be of help? This is something that might be better off asked at a community of Anaconda experts.
