Combine​Media​Queries in Sublime Text3 why doesn't it work?
Does anyone use it? Help me please.
I did not quite understand what was required of me in the description

Configure
Set the bin_path in Preferences: Package Settings > CombineMediaQueries > Settings – User to the location of the Node bin path:
{
"bin_path" : "/usr/local/bin"
}

I just pasted this piece of code into user settings.
