"Couldn't find index for terminaltables" while installing evillimiter

I'm trying to install evillimiter but it doesn't run as there is something wrong with "terminaltables". I've installed Python 3.6.5 and have made sure it's fully installed. I installed it on the same machine but with only 2GB of ram allocated and it worked however when I installed evillimiter with 4GB of ram allocated this error appeared. Just a wild guess, does it need ram free to work? I only had less than 1GB ram free.

Here's a screenshot of what the error looks like when I tried to install evillimiter. I've highlighted where the error is and what it says.
