When compiling Twitter\'s Bootstrap 2.3.2. with Less 2 i found to following error:
NameError: #grid > .core > .span is undefined in /home/bootstrap-2.3
I was able to avoid the error without modifying Bootstrap files by creating a new mixin that loaded after the Bootstrap mixins:
#grid {
.core {
.span(@gridColumns) {
width: (@gridColumnWidth * @gridColumns) + (@gridGutterWidth * (@gridColumns - 1));
}
}
};
This was better for us as we avoid patching contrib packages.
