Programmatic Ponderings

Hi, I was looking to use your object-tracking-blogpost, it is really amazing work.
I followed the instructions on the github page but sadly when I try to compile the files I get this error which you seemed to have mentioned a fix for by editing the .bashrc file but it does not work is there another reason why I might be getting this error.
Thank you

Didn’t know about Dilinger.io for Markdown editing. It looks nice! Thanks for the link. I am currently using Stackedit beta ( https://stackedit-beta.herokuapp.com/# )
