SCSS Mixins File not Being Loaded - css

Question

I have received a bunch of front end code to integrate with my existing Rails application. The other developer used SCSS, and structured their files like so:
styles/styles.scss
#import "mixins";
#import "1-settings/colors",
"1-settings/fonts",
"1-settings/sizes";
#import "2-generic/reset",
"2-generic/normalize",
"2-generic/structure";
#import "3-base/body",
"3-base/headings";
#import "4-components/buttons",
"4-components/forms",
"4-components/grid",
"4-components/section";
#import "5-objects/banner",
"5-objects/card",
"5-objects/footer",
"5-objects/header",
"5-objects/mobile-nav";
#import "6-pages/404",
"6-pages/about",
"6-pages/application",
"6-pages/dashboard",
"6-pages/home",
"6-pages/profile",
"6-pages/signup",
"6-pages/training";
#import "utility";
In 2-generic/reset, a mixin I defined in my _mixins partial was #included, however I continuously receive the error:
Sass::SyntaxError in Pages#index
Undefined mixin 'vendor'.

I have tried changing the order of everything, moving everything into the same directory, and moving/removing/adding *= requires in the application.css file to no avail.
What am I doing wrong?

Answer 1

Try moving the mixin you're trying to include to the top of your reset file and see if you still get the error.
Maybe it's a simple mixin definition problem or name misspelling, if it works then you know there's a problem with the imports.
