I'm having trouble following the instructions at https://www.jetbrains.com/phpstorm/help/transpiling-sass-less-and-scss-to-css.html. I've installed Ruby, but this instruction isn't clear for me:
Specify a path variable for the folder where the Ruby executable file and the gem.bat file are stored. This lets you launch Ruby and Gem Manager from any folder and ensures that Ruby is successfully launched during transpilation.
I've searched a lot online and I've found a lot of related information but nothing that actually explains what to do clearly. Setting up on my MacBook was easy, but I'm stuck on by Linux Mint installation (which, obviously, I'm relatively new to!).
