Linting package linter-scss-lint was not working properly for me, with no linting occurring and no errors thrown. On top of that, other linters were functioning properly (i.e. linter-jshint). Came across issue Linters not linting…, and one comment suggested opening Atom from the command line. Tried this, and linter-scss-lint began working properly. Upon further searching, found issue noting that $PATH only present when Atom is launched from the command line.

Look in to this with Sam, he’s not having the same problems even though our .bash_profile and .bashrc files are the same. Check versions of Atom, all packages, Ruby, etc.
