butterfly: command not found

[zwhitchcox]

I get a butterfly: command not found error when trying to install using pip on ubuntu 17.10.

I know little to nothing about python, so that's about all I'm going to be able to tell you. I tried python and pip 2.7 and 3.6. I'm not sure if I'm supposed to add something to my path or anything, but I didn't see anything in the readme

After installing you can see that butterfly python script located in ~/.local/bin
I have solved this problem by adding to your ~/.bashrs or ~/.zshrc
this line:
export PATH=$PATH:~/.local/bin

or just enter this in terminal for fast checking if it is works.
