TypeError: Object #<Object> has no method 'hypot'

[ElSebita]

Hello.
I followed the instructions, I installed everything including patel-c as global. make throws that error.
I installed es6-math as global, which is said to provide Math.hypot but still can't build.
Fedora 22.

/home/meneldur/Downloads/Iosevka-master/node_modules/libspiro-js/libspiro.js:218
        r[i].seg_ch = Math.hypot(dx, dy);
                           ^

Well installing Math.hypot globally cannot solve this problem. You can install the core-js in the repository directory and add the following code to the beginning of generate.js (and maybe extract.js):

require('core-js');

BTW, AFAIK the latest Node has built-in support for Math.hypot, as well as Symbol.iterator.

core-js was installed. Adding that line of code to generate.js and extract-js solved the problem.
Thanks!
