'Deprecation Warning in Bootstrap SCSS

I am trying to create custom bootstrap by importing only the required components into a style.scss file from bootstrap sass. However, I get a chain of many Deprecation Warnings when I import and compile the 3 required components.

SCSS:

@import "./bootstrap-4.3.1/scss/functions";
@import "./bootstrap-4.3.1/scss/variables";
@import "./bootstrap-4.3.1/scss/mixins";

Console Warning (first of the many):

Deprecation Warning: Using / for division is deprecated and will be removed in Dart Sass 2.0.0.

Recommendation: math.div($spacer, 2)

More info and automated migrator: https://sass-lang.com/d/slash-div

    ╷
298 │ $headings-margin-bottom:      $spacer / 2 !default;
    │                               ^^^^^^^^^^^
    ╵
    bootstrap-4.3.1\scss\_variables.scss 298:31  @import
    style.scss 3:9                               root stylesheet

I am using the following versions of tools:

Bootstrap: 4.3.1, Sass: 1.33.0 compiled with dart2js 2.13.0

Is anything wrong with using this version combination, or any other issue? How can I resolve it?

Solution 1:[1]

I found a solution here.

Essentially, what I understand is that a new version of SASS is throwing warnings. You can downgrade your version to stop the warnings for now and doing so shouldn't break anything either.

tl:dr You should use Sass: "1.32.13" instead.

Solution 2:[2]

If You wanna resolve this issue You can review sass options from Sass-lang

and add the best option for your sass

In my case, I have this issue

Deprecation Warning: Using / for division outside of calc() is deprecated and will be removed in Dart Sass 2.0.0.

So I added "quietDeps" option to my sass

 .pipe(sass({
            outputStyle: 'compressed',
            quietDeps: true
    }).on('error', sass.logError))

and worked correctly after run my tasks again
