'Errno::ENOENT: No such file or directory' - Help with starting up Sass please.

Hi, James:

A long-time user of Sass on Windows here (and currently).

First and foremost, I highly recommend using SassMeister or Codepen to follow along the class quickly and conveniently.

Second Parameter for the desired output filename is needed

When it comes to your problem, do realize that you must be both in the correct directory with your cmd and pass in as a second parameter what you want the the .scss or .sass to be called. The same applies with the -w option.

# test.sass 

div 
  width: 40vw 

If you just type sass t.sass the following will happen in the terminal:

sass test.sass 
div { 
  width: 40vw; 
}

You need to type in the name you want the outfile file to be if you want it to compile a specific file instead of a specific folder:

sass test.sass test.css 

That will create test.css. The better way is to watch the file of course for sass to autoiupdate things; things are a bit different

sass --watch test.sass:test 
>>> Sass is watching for changes. Press Ctrl+C to stop. 

You give an option parameter to sass to inform it to deviate from its normal behavior to watch instead a specific file and folder. Based on the rules established by the method, it expects an input file or folder separated from what you want the output to be by a colon (:)

Correct Directory

Make sure you're in the correct place. Your terminal or cmd should have started inside your user folder. From there, you should have been able to navigate to your desktop:

cd desktop
sass test.sass test.css 

If that's not working, feel free to reply and I'll reply as soon as I'm able to.
