For my main.css to be updated , why I must retype sass --watch main.scss:main.css every time??

Hello everyone,

I hope someone can tell me why the changes i am making are not automatically updating.

Here is my issue for 2 different scenarios :

first scenario:

1. when both my main.scss and main.css have the same code for example:

body { background: red; }

then i type sass --watch main.scss:main:css

the cmd prompt displays >>> Sass is watching for changes. Press Ctrl-C to stop.

1. when ever i make changes in my main.scss nothing changes in the main.css

second scenario:

1. I first make a change in the main.scss

2. i type sass --watch main.scss:main.css

3. the cmd promt displays

Sass is watching for changes. Press Ctrl-C to stop. write main.css write main.css.map

1. when i go back and click on the main.css an alert reload message pops up. then the changes gets updated in the main.css

2. here is the issue: I have to exit and rerun sass --watch everytime i make a change in the main.scss for the main.css to be updated.

I apologize for the long message but i would appreciate it if anyone can help me out. Thanks
