The syntax for Sass Web Fonts has changed.
What would previously have been written:
@include web-fonts("Open Sans");Should now be written:
@import url(web-fonts-url("Open Sans"));This change was made to allow Sass Web Fonts to be used with libsass.
If you have a large project with lots of calls to web-fonts() that you don't want to replace by hand, you can include web-fonts/compat.scss from the Sass Web Fonts repository and replace any occurrence of @import "web-fonts" with @import "web-fonts/compat" to continue using the old syntax. However, it is recommended that you switch to using the new syntax at some point, because web-fonts/compat will be removed in a future release of the library.
