Could not find an option or flag "-l"

I tried typing:

sass -l app.scss

in my terminal and I received an error message:

Could not find an option or flag "-l"

Is the -l flag supported anymore?

Did you try sass --help to see if it is listed? Mine shows under input and output:

Usage: sass [options] [INPUT] [OUTPUT]

Input and Output:

-l, --line-numbers               Emit comments in the generated CSS indicating the corresponding source line.
    --line-comments

I tried in a workspace and it appears to be there:

treehouse:~/workspace$ sass -l app.scss                                                   
/* line 3, app.scss */                                                                    
body {                                                                                    
  background-color: orange; }

and on my Mac I see the same

kris$ sass -l app.scss
/* line 3, app.scss */
body {
  background-color: orange; }

Thank you for the reply. I do not have the -l flag when I run Sass help. I am running Sass version 1.21.0
