• [ ] Other... Please describe:

What is the current behavior? (You can also link to an open issue here) Issue #414

What is the new behavior? Fixed the issue by removing ./ prefix from paths and setting Elixir paths in config.

Does this PR introduce a breaking change?

• [ ] Yes
• [x] No

Other information: This fix is kind of a 'hack' for a bug in Elixir, it will have to be changed in the future. I changed the gulp file from using absolute paths with ./ prefix to using relative paths by setting elixir paths in config. However, the styles mixin needs to override elixir path config using ./ prefix (works just fine here!) which looks ugly.
