Variable Name Error “is undefined” even though “variables.less” imported

Question

I started using LESS today. But it\'s kinda weird. This code does not work. I get an error:

! Variable Name Error: @linkColor in a is undefined.

Answer 1

For me its happened when using @Import-once and nothing help. but with @Import its worked.

as i read in the last version of the Less the Import will work as Import-once.
