It seems to me that there is some problem in the line background-image: url(../img/icon/@path); that you need something like /{@path} or /@{path} ... But I can't figure out how (

Answer 1

write the path as a string and output the variable as a string

.dest(@path) {
  background-image: url('../img/icon/@{path}');
}

.icon-1 {
  .dest('icon-1.png');
}
