[Compile]
C:\test\assets\css\main.less -> C:\test\assets\css\main.css

Expected ')' but found ' ' on line 20 in file 'less/mixins/image.less':
 [19]: // spelling of `min--moz-device-pixel-ratio` is intentional.
 [20]: .img-retina(@file-1x; @file-2x; @width-1x; @height-1x) {
       --------------------^
 [21]:   background-image: url("@{file-1x}");

How to repair this?

Answer 1

The LESS-build-sublime plugin seems to use the dotless LESS compiler. This .NET LESS compiler supports the language features up to version 1.3.0.

The source code of Bootstrap however uses a LESS compiler at version 2.1.0. Bootstrap depends on one of the language features that doesn't exist in version 1.3.0.
